Direct-to-Direct (D2D) satellite connectivity is one of the most talked about innovations in IoT right now. It promises seamless global coverage, allowing connected devices, from smartphones to smart sensors, to communicate with satellites without the need for additional hardware such as a specialized antenna.

At first glance, D2D sounds like the ultimate solution for remote IoT applications. But there’s a problem: the term is being used too broadly and too optimistically. Many assume that D2D is synonymous with standards-based satellite IoT, like NTN NB-IoT or LTE Cat-1 over satellite. In reality, these are adjacent but distinct technologies, each with very different capabilities, timelines, and trade-offs.

In this post we’ll cut through the noise to discover what’s actually available today, and what will be available in six months, one year, and beyond. We’ll look at the benefits and limitations of D2D, and explore whether you would be better off focusing on standards-based satellite IoT as you consider what’s best for your IoT deployment.

What Direct-to-Device (D2D) Actually Means

Direct-to-Device (D2D) connectivity means that a device – typically a smartphone – can communicate directly with a satellite (part of a non-terrestrial network, or NTN) without requiring additional external hardware like a specialized antenna / dongle.

D2D is a capability, not a standard. It means a device can talk directly to a satellite, but that doesn’t necessarily mean it uses NB-IoT or LTE.

The most well-known example is Apple’s agreement with Globalstar. Newer iPhones embed chipsets that allow them to access the Globalstar satellite constellation where available. This is a proprietary technology, meaning iPhones cannot connect to other satellite networks.

While still relevant, the Globalstar/Apple partnership is an outlier. Today, D2D is often referenced in the context of standards-based connectivity – but that’s where definitions start to blur.

D2D and Standards-Based Connectivity: Not the Same Thing!

Standards-based NTN connectivity refers to satellite networks that adhere to existing cellular standards, e.g. NB-IoT and LTE Cat 1.

A key benefit of this is that you don’t have to modify your data to send it through a proprietary satellite protocol. Standards-based connectivity also opens the door to switching networks for broader coverage or better pricing – a flexibility not available with proprietary solutions.

But here’s the key distinction:

D2D

Standards-Based NTN

D2D is about the physical capability for a device (e.g., smartphone or sensor) to connect to a satellite without extra hardware.

Standards-based is about ensuring that the satellite connection adheres to existing cellular protocols like NB-IoT and LTE Cat 1.

The connection can be proprietary or standards-based.

Compatible devices may still require separate hardware to connect, especially today.

Pure D2D for IoT is limited today and requires ideal antenna positioning and sky visibility.

You can access standards-based NTN today, usually via an external transceiver / dongle.

What’s Available Now (Early 2025)?

There are two cellular standards being adopted by satellite network operators: NB-IoT and LTE Cat 1.

  • NB-IoT uses very little bandwidth and is being rolled out by providers like Iridium and Viasat to complement their proprietary solutions.
  • LTE Cat 1 requires more bandwidth and is being pursued by newer entrants like Starlink and AST SpaceMobile, who partner with mobile network operators (MNOs) to access spectrum.

 

The standard closer to delivery is NTN NB-IoT. Skylo is not a satellite network operator, but has done a lot of work to make NB-IoT work over existing satellite networks. They have partnered with multiple satellite networks, including Viasat and Ligado Networks, to bring a solution to market in the USA, Canada, Australia, New Zealand and Brazil.

Some satellite network operators are already offering this service in a limited capacity – Sateliot were among the first to market with a proposition. However, they’re in the process of scaling their satellite IoT services; initial store-and-forward services are available, but fully operational coverage will be c. 2028.

At the moment, the hardware being built for IoT tends to take the form of a unit that can be attached to a sensor or gateway to facilitate NTN connectivity.

Why is Separate Hardware Still Needed for IoT?

  • Many sensors or gateways don’t yet support NTN NB-IoT or LTE Cat 1 and will need to pass data through a connected device which can re-format the data to work with the appropriate standard.
  • Satellite connectivity requires a clear view of the sky. Devices embedded in machinery or under panels (like an OBDII port or solar-powered sensor) are unlikely to maintain a reliable satellite link.

What Will Be Available In Six Months (Mid-Late 2025)?

In terms of NB-IoT, Viasat’s “IoT Direct” is currently in beta mode, before a full release in the second half of 2025. This will deliver global NB-IoT capabilities for connected devices, and we’re particularly excited about this development.

We also expect the first LTE Cat 1 service for IoT from Starlink to be available before the end of 2025. Starlink’s “D2C” model depends on cooperation from mobile network operators, and rollout will begin in countries with large land masses and low population density, where unused spectrum is more available.

Current rollout countries are the USA, Canada, Australia, New Zealand, Chile, Peru, Ukraine, Switzerland, and Japan.

What Will Be Available in One Year?

We should see more integrated, true D2D devices that can connect to both cellular and satellite networks using standard protocols, without needing separate antennas. But these are unlikely to be materially lower cost than the current, proprietary options available. This is because it is both economies of scale and competition that drives prices down, and that will take a little longer to come to fruition.

Starlink will likely have its first competitor in the LTE space (no pun intended) with the commercial launch of AST SpaceMobile anticipated in early 2026. However, AST SpaceMobile is focused squarely on the cellphone market rather than IoT devices; it will probably be another 12 months (early 2027) before IoT devices can connect to the AST SpaceMobile network. It’s also worth mentioning that AST SpaceMobile also needs agreements with MNOs to deliver its service; it will not be global at launch.

The Future (2-5 Years)

The update that allowed cellular standards to be used over satellite is called 3GPP Release 17. While Rel-17 made it possible to use cellular standards in satellite communication, it didn’t make it easy, with companies like Skylo having to do a considerable amount of engineering to make NB-IoT transmissions over satellite a reality.

Iridium, currently the world’s only global satellite IoT network, was a little late to the party in developing a standards-based proposition, but now that it is, it’s working very closely with the 3GPP to extend the functionality of NTN NB-IoT. This collaboration means that 3GPP Release 19 (anticipated in late 2025) will remove many technical challenges and hasten the widespread availability of industry standard chipsets.

Availability of Standards-Based NTN Services

*3GPP compliant release 10 or newer, modem must support existing bands of operation in intended service countries

We also anticipate that we’ll see increased data throughput, greater power efficiency, and lower latency as these advanced protocols coupled with new satellite modems filter through, enabling smaller, lower cost and longer lasting IoT devices.

The reason this falls into the 2-5 years section is because the benefits take several years to reach end users. Firstly, network operators, device manufacturers and other industry stakeholders will need time to implement the new standards, which can involve significant hardware and software updates, plus extensive testing.

Deployment of the new technology across networks is often piecemeal, too, rolled out across regions and service providers at different times – meaning that it will take time to become widely available. And, of course, end users’ devices must be compatible with the new standards; this will include firmware changes to support the lower speeds and smaller message sizes available over NTN NB-IoT.

While NB-IoT remains the most popular choice for delivering NTN standards-based connectivity, by this time we’d anticipate also having IoT propositions from AST SpaceMobile and Lynk using the LTE Cat 1 standard. These new satellite network operators, along with Starlink, will undoubtedly create more commercial agreements with mobile network operators, extending the reach of NTN LTE Cat 1 services.

What Should IoT Businesses Do Now?

It depends on the criticality and data requirements of your application. While NTN NB-IoT services are reaching the market, the throughput is very small, and data transmission is infrequent, so it best serves applications where there are a high number of end points, but real-time information is not required (e.g., livestock tracking, environmental monitoring, agriculture, basic fleet management, and wearables).

Massive IoT vs Critical IoT Diagram

If this describes your application, get in touch with a service provider like Ground Control to get advice on the best network and hardware for your application. Note that this will almost certainly involve additional hardware, as the satellite industry is some way from solving the issues around device compatibility and antenna siting mentioned earlier.

If you need higher volumes of data and closer to real-time data, you will still be better served by a proprietary solution such as IMT / Certus 100 from Iridium, or IoT Nano from Viasat. These services are well established and globally available; they will co-exist alongside the standards-based solutions for the foreseeable future.

Finally, don’t get too preoccupied with D2D; it offers exciting possibilities, but it’s still a developing technology that won’t be widely available for some time, and will only be appropriate for certain use cases.

Critical national infrastructure is an increasingly attractive target for state-sponsored activists and extremist groups. Remote infrastructure – everything from outstations to wind farms, wellheads to pump stations, haul roads to transport hubs – is particularly vulnerable because of the challenges in creating robust security solutions in these locations. This blog post seeks to present a solution to these challenges, but first, let’s dig into the issues in more detail.

The Growing Threat to Remote Infrastructure

The vulnerability of utility and energy production sites to cyber attacks is well documented; from 2023 to 2024, US-based utilities experienced a 70% surge (Reuters). Less frequently reported is that physical attacks on infrastructure also rose 73% from 2020 to 2022 (Axios), with incidents including a gunfire attack on two substations in North Carolina, USA, which left 45,000 customers without power.

In Nigeria, in early 2024, the power sector faced escalating vandalism of high-voltage transmission infrastructure; incidents tripled during a 15 week span, including explosives being used to destroy transmission line towers (The Electricity Hub).

In Australia, thefts from unmanned construction sites reached a 10 year high in September 2024, with a 22% increase in theft-related offences during the same period (Herald Sun). And in the UK, the cost of theft of agricultural equipment escalated to an estimated £52.8 million in 2023, a 4.3% increase from the previous year (NFU).

In addition to a growth in isolated incidents is the underlying strategy to destabilize infrastructure, driven by alliances between state actors like Russia, and organized criminal gangs. These activities include sabotage, arson and cyber attacks, aimed at undermining critical infrastructure (The Guardian).

Attacks are increasing: companies, governments and individuals with hard-to-protect, high value assets are fighting a rising tide of criminal activity.

The Challenge of Traditional Security Measures

The infrastructure we’re describing here – transport, energy production, heavy industry – operates across vast areas, making it impractical to station physical security at every location which could be a target. Assuming a single security guard is stationed at a site for 8 hours a day, 7 days a week; the cost of an unarmed guard would be c. $3,600, and c. $6,000 for an armed guard (Deep Sentinel).

Statistically, most theft takes place after dark, and are more frequent in winter; long weekends and holidays are also attractive (Site Watch Group). Thus, 24 hour cover would be prudent at least over weekends, adding substantially to the cost.

Security-Guard-in-Remote-Location-shaded-blue

Another option is to use fences coupled with cameras and sensors to detect intruders, and provide real-time alerts to a remote monitoring center. The security personnel there can monitor multiple sites remotely, reducing on-site staffing costs. Upon receiving an alert, they can choose to dispatch security personnel to the affected site, alert local law enforcement or trigger some localized deterrent such as alarms, voice sirens or lights.

The pros of this approach is that it’s lower cost, delivers 24/7 surveillance, and can be rapidly and cost-effectively scaled up. However, it requires a reliable, secure and cost-effective means of transmitting the video stream (and potentially also audio and movement sensors). Within cellular connectivity this is pretty straightforward, but in a remote site, satellite is often the only viable option.

Remote-Surveillance-Smart-Fence-shaded-blue

Finding the Right Satellite Connection for Remote Surveillance

Satellite connectivity isn’t a homogenous blob. There are multiple radio frequencies used, and the type used strongly influences the form factor of the satellite transceiver. For example, people seeking broadband internet access over satellite – Starlink, Hughesnet, OneWeb etc. – will be using Ka-band, as this supports higher data rates, and there’s plenty of bandwidth available (i.e. limited congestion issues).

The drawback of Ka-band is that it is both susceptible to rain fade (signal loss in bad weather), and the antenna size is large, power hungry, and needs to be precisely positioned. This is not an issue for home installation, but in a remote outstation, there may be mountains, trees or the outstation itself preventing the ideal siting of the antenna.

The fix to this – phased array antennas which electronically steer themselves to optimal positions – has the drawback of consuming significantly more power. Indeed, it would be challenging to power any Ka-band antenna via a solar-powered battery, particularly for the sorts of continuous operation that a surveillance system requires.

Satellite Frequency Bands

Satellite services that operate in the L-band spectrum, on the other hand, have very small antennae, and low power requirements compared to Ka-band. Iridium and Viasat (previously Inmarsat) utilize L-band for data transmission, which makes them perfect for IoT applications where the data requirements are lower, and a small, discreet, battery-operable antenna is an asset – sometimes a necessity. L-band transmissions are unaffected by weather conditions, and very hard to intercept, making them ideal, in principle, for mission critical applications like remote surveillance.

However, video streaming from remote, potentially unpowered locations, is an awkward fit for both Ka- and L-band. It’s a high bandwidth transmission, but as discussed, high bandwidth satellite services are power hungry, easy to identify (and therefore to put out of action), and difficult to position. L-band fixes all those challenges, but to send video over L-band, which is a much more constrained frequency band, is very expensive.

Until now…

A Breakthrough in Remote Video Surveillance

There have been two key developments that have made it possible to send video over an L-band satellite connection cost-effectively. The first is the advent of low bandwidth video. Our partner Videosoft has developed video compression and transmission technology that delivers real-time, low-bit rate video. They’ve coupled this with an image enhancement feature that lets users specify and download high-res pixels from an area of interest in a scene.

Videosoft’s technology works with most off-the-shelf hardware, including video cameras, CCTV, audio microphones, GPS tracking antennae, and other I/O devices.

Watch Videosoft Demo

The second development is the availability of midband (higher throughput) transmissions in the L-band spectrum; notably Viasat’s IoT Pro service, and Iridium’s Certus 100 service. The latter is particularly well suited to remote surveillance because the satellites are in Low Earth Orbit, which means the latency is very low – critical when you need real-time alerts if a facility has been penetrated, or an asset is moving outside of schedule. 

Additionally, Iridium has a cross-linked network of 66 satellites, which means you don’t need to point your antenna at the satellite; if your facility or asset is in a wooded or mountainous area, this could be a critical advantage. 

RockREMOTE Rugged: A Simple and Secure Solution

There are a number of Iridium Certus 100 transceivers available – we design and build several ourselves – but the one we’ve focused on for remote surveillance is the RockREMOTE Rugged. This is because, most importantly, it has the compute power to natively run the Videosoft program without needing any additional hardware. It’s simply a matter of plugging your camera into the RockREMOTE, and working through some simple config steps to get started.

RockREMOTE Rugged is very easy to install; it’s IP67 rated, and designed for permanent outdoor installation in harsh environments. Its omni-directional passive antenna is small and discreet, making it harder to identify by bad actors.

RockREMOTE Rugged

Thus, securing a remote site becomes smarter and more cost effective. Choose from a very wide range of cameras, audio equipment, motion detectors etc., then plug them in to the RockREMOTE Rugged. The onboard Videosoft technology will compress the data so it can be sent cost-effectively over the Iridium Certus 100 network, in real-time, to your remote monitoring center.

A Smarter Approach to Remote Security

Protecting remote infrastructure has never been more critical – or more challenging. While traditional security measures struggle to balance cost and coverage, the combination of low-bit rate video, real time image enhancement, and power efficient satellite connectivity presents a game changing solution.

With RockREMOTE Rugged and Videosoft’s technology, organizations can deploy surveillance systems that are reliable, cost effective, and optimized for remote environments. Whether safeguarding critical national infrastructure or protecting high value assets, this technology ensures security teams have the visibility they need, when they need it most.

Undersea internet cables are essential for global communications and economic security. The entire global network of cables is more than half a million miles long and comprised of more than 200 independent but interconnected systems. These cables span vast distances, connecting continents and enabling everything from international internet services to military communications. But with increasing geopolitical tensions and the growing importance of digital infrastructure, the threat to these cables has risen on the international agenda.

The strategic importance of undersea cables, which carry 99% of international telecommunications, makes them attractive – and vulnerable – targets.

In January 2025, the Royal Navy closely monitored the Russian vessel Yantar, officially an ocean research ship but considered a spy ship, as it entered UK waters and mapped underwater infrastructure.

Additionally, a NATO flotilla, including ships from the Netherlands, Germany, and France, assembled off Estonia to protect undersea cables in the Baltic Sea from potential sabotage, primarily by Russia.

Guard and patrol vessels play a pivotal role in deterring and responding to potential threats, ensuring the integrity of essential communication networks.

Map-of-Undersea-Cables-2

Data from the TeleGeography Submarine Cable Map shows that damage to undersea cables is a common occurrence. According to a report by the International Cable Protection Committee (ICPC), around 300 cable breaks are reported every year. Most of these are accidental, caused by fishing trawlers, ships’ anchors, or natural events like earthquakes. However, the risk of deliberate attacks or sabotage by state or non-state actors is also increasing.

The potential for geopolitical tensions to spill into the maritime domain has been highlighted in various reports. For instance, the United States Department of Defense (DoD) has raised concerns about the vulnerability of critical undersea infrastructure to foreign adversaries. This type of attack can have devastating effects on global data flow, cybersecurity, and national security.

Internet traffic, military transmissions and financial transactions all depend upon submarine cables, so any disruption can cause significant economic damage, loss of access to critical services, and widespread instability in communication.

Undersea-Cables

The Role of RockFLEET in Securing Submarine Cables

Guard boats are increasingly deployed as vital protectors of undersea cabling infrastructure. These guard boats, often repurposed fishing vessels, act as sentinels over subsea cables, ensuring their security by warning nearby vessels to keep a safe distance.

Tracking guard boats efficiently in remote and challenging maritime environments requires an advanced tracking solution. RockFLEET is a compact, robust, and highly reliable tracking device designed specifically for use in harsh maritime conditions. It operates through satellite-based communication via the global Iridium network, ensuring seamless tracking of guard boats even in areas with no cellular coverage, anywhere in the world.

This capability is essential as guard boats often patrol vast stretches of ocean far from terrestrial networks. With RockFLEET, maritime authorities and operational teams can monitor the precise location of each guard boat, ensuring the vessels are where they need to be to protect the cables effectively.

RockFLEET-Being-Held-by-Sailor

Three Ways RockFLEET Supports Guard and Patrol Vessels

Real-time Positional Data

One of the key features of RockFLEET is its ability to provide real-time positional data, which allows maritime coordinators to track the movement of guard boats and assess their effectiveness in securing undersea cables. If a guard boat drifts away from its designated patrol zone, RockFLEET alerts the operational team, enabling quick corrective action. This constant monitoring ensures that no section of the subsea cable remains unprotected due to navigational drift or unforeseen circumstances.

Estimated Arrival Times

Another critical function of RockFLEET is providing estimated arrival times (ETA) for guard boats. When repositioning guard boats due to shifting threats, adverse weather conditions, or maintenance schedules, knowing the vessel's precise ETA is crucial. RockFLEET transmits accurate ETA data, allowing for better planning and coordination. This information helps ensure that there are no gaps in cable coverage and that another vessel is available to take over if one needs to leave its position.

Enhanced Vessel Safety

Safety is also a significant concern for guard boat crews. Since these vessels often operate in remote and sometimes hazardous conditions, having a reliable tracking system ensures that their locations are known at all times. In case of an emergency, RockFLEET provides real-time location updates, enabling rapid response and assistance from support teams. This enhances the overall security of both the vessels and the critical cabling infrastructure they protect.

The Future of Undersea Cable Security

As the threats to undersea cables continue to evolve, governments, cable operators, and multinational organizations are increasingly prioritizing the security of this infrastructure, given its direct impact on everything from national security to economic stability. New initiatives like the UK’s ‘Nordic Warden‘, which aims to track the movement of vessels suspected of malicious damage, should enable faster response times.

Guard boats and patrol vessels in their preventative capacity will remain an essential part of this response. RockFLEET plays an essential role in ensuring the effective tracking and monitoring of guard boats tasked with the protection of undersea cables. By providing accurate location tracking, monitoring movement, estimating arrival times, and enhancing overall vessel safety, RockFLEET helps to safeguard the vital cable infrastructure that underpins global communication and commerce.

Protect Critical Infrastructure with Smarter Maritime Monitoring

As threats to undersea cables and maritime assets increase, guard and patrol vessels play a crucial role in safeguarding global communications. Our advanced satellite tracking and monitoring solutions ensure these vessels operate with maximum efficiency, real-time situational awareness, and enhanced safety – no matter how remote the mission.

What is D2D?

D2D refers to the ability for an unmodified device – such as a cellphone – to access satellite connectivity. This was pioneered by Apple and Globalstar as they partnered to provide an emergency satellite communication service for iPhone users in 2022.

How Does D2D Work?

There are two ways D2D can be delivered. The first is by building a chipset into the device that allows it to access a specific satellite network. This is the option chosen by Apple, and its satellite network partner Globalstar. The benefit of this approach is that Globalstar has licensed radio spectrum that allows it to provide a service anywhere where it has a satellite overhead. The downside is that the device can only communicate with a single satellite network.

The second way to deliver D2D is to adapt the satellites themselves so that they are compatible with the communication protocols already in use by cellphones and other devices – i.e. 4G, 5G etc. This is the approach chosen by Starlink, AST SpaceMobile and Lynk, all of whom are in the process of launching satellites compatible with terrestrial network communication standards.

The benefit of this approach is that, in theory, all compatible satellite networks are available to the cellphone user as simply another network on which to roam, and they can do so depending on what their commercial agreement is with their usual network service provider (e.g. Vodafone, AT&T etc.).

The downside is that because these are new satellite networks, they do not have licensed radio spectrum through which to deliver their service; this is already distributed among older, more established satellite constellations. So to deliver service, the new satellite network operators need to partner with a terrestrial network operator to ‘borrow’ some of their licensed radio spectrum. Services are only available where these partnerships exist, so they are not global. Starlink, for example, has partnerships in 10 countries; outside of these countries, it cannot provide service.

How Could D2D Benefit Lone Workers?

In 2021, we asked lone workers across multiple industries if, as part of their job, they sometimes or often travelled out of cellular coverage. 51% responded yes. We then asked about the implications of this; did they ever feel unsafe, for example, or been unable to send or receive a message when they needed to.

Statistics on Lone Worker Safety

 

As the graph illustrates, lone workers operating in areas without voice, text or internet services feel – and are – more vulnerable. 15% of the overall workforce are considered lone workers, and NSC data indicates that working alone increases both the likelihood of incidents, and the severity of adverse outcomes.

Although we can’t draw a parallel, it’s striking that industries with a high number of lone workers – Utilities & Renewables, Oil & Gas, Forestry, Emergency Response, Community Healthcare – are also struggling with staff retention.

 

While it’s not a silver bullet, the benefits of lone worker monitoring technologies are well documented: improved safety outcomes and staff morale, leading to greater staff retention, and saved costs in recruitment and insurance premiums.

An estimated 2.3 million lone workers in Europe, North America, and Australia & New Zealand now have access to a lone worker safety solution, with the market estimated to grow at a rate of 7.1% between 2024 and 2029 – further indication of the value of these platforms.

But if they can’t be accessed because the worker is outside cellular coverage, they fail. D2D with its ability to confer internet access to any compatible cellphone with a relevant commercial agreement, unlocks the ability to access these platforms from very remote locations where cellular coverage is nonexistent.

Why Your Cell Phone May Fail You

The problem with D2D is not the service, it’s the cellphone. Relying on a standard smartphone for emergency or indeed routine satellite communication comes with significant weaknesses, especially when it comes to the device’s physical vulnerabilities. Here’s why your phone may not be the most reliable option when you need it most.

Overheating and
Thermal Shutdowns

Satellite connections require the phone to transmit at higher power levels, which generates more heat than cellular communication. Many phones will automatically shut down when internal temperatures exceed safe limits, leaving users without a means of communication.

Drop and
Impact Vulnerability

A cracked screen or internal damage from a fall can render a phone unusable, preventing emergency communication. Even flagship smartphones can shatter from waist-high drops, whereas ruggedized satellite communicators are built to withstand extreme impacts.

View Data Source

Battery Drain and Cold Weather Failure

Phones in satellite mode will often use higher transmission power and spend more time searching for signals, draining the battery faster. Further, cold weather severely affects lithium-ion battery performance.

Lack of Physical Controls for Emergency Use

In emergency situations, speed matters. Unlike dedicated satellite devices, which often feature an SOS button that can be activated instantly, smartphones rely on touchscreen controls that may be difficult to use with wet, cold, or gloved hands.

View Data Source

Weak Antenna and Poor Signal Reception

Smartphones' internal antennas are optimized for terrestrial networks, meaning signal reception in satellite mode will often be weaker and less reliable. Dedicated satellite communicators feature larger antennas that ensure consistent connectivity even in difficult environments.

In today’s interconnected world, digital threats have reached a scale never seen before.

In 2023, rising global tensions led to a surge in cyber threats and disruptions to critical infrastructure worldwide. Escalating conflicts – such as those involving Ukraine and Russia, Israel and Hamas, and nations in the South China Sea – motivated hackers to exploit critical infrastructure for control and financial gain. Globally, ransomware incidents are increasing across every continent, as the map shows. At the same time, ransomware attacks targeted more industrial organizations, with reported incidents increasing by nearly 50 percent [Dragos report 2023].

Illustration showing the number of reported ransomware attacks by continent Illustration showing the number of reported ransomware attacks by continent

Cyber attacks can target everything from financial institutions to healthcare systems, transportation networks and power grids – and it’s of increasing concern to the general public. In January 2025, Ground Control conducted a survey of 500 US adults which revealed that over 65% were concerned about cyber attacks on critical national infrastructure, with 70% having limited to no confidence that essential services are protected from cyber attacks.

Utility providers are now facing an alarming new reality where cyber attacks increasingly threaten the safety of their operations. Indeed, Utilities is the second most targeted industry for ransomware attacks, experiencing a 270% increase in data violation cases between 2020 and 2023.

The 2021 Colonial Pipeline Attack

The 2021 Colonial Pipeline attack served as a wake-up call, underscoring the vulnerability of the utility sector to cyber threats. Hackers used a virtual private network (VPN) to infiltrate the pipeline’s control systems, causing widespread fuel shortages across the US East Coast. The incident led to a ransom demand of $5 million, which was ultimately paid to regain control of the pipeline.

The financial costs of data breaches are staggering. According to IBM’s 2021 report, the average cost of a data breach rose to $4.24 million. These costs go beyond the immediate exposure of data and include downtime, loss of revenue, and long-term reputational damage. Utilities must be proactive in defending against such threats to avoid crippling financial losses and operational disruptions.

The Hidden Vulnerabilities in Utility Networks

Utility companies depend heavily on SCADA (Supervisory Control and Data Acquisition) systems to monitor and control infrastructure. These systems collect and transmit data from Remote Terminal Units (RTUs), often located in remote or hard-to-reach areas. However, these RTUs present a significant security vulnerability. With 90% of utility customers reporting “limited to no visibility” into their industrial control systems, once a hacker gains access, they can easily monitor, manipulate, and potentially sabotage critical infrastructure [Dragos report, 2020].

It’s crucial for utilities to address this blind spot and implement solutions that safeguard the data extracted from RTUs and transmitted to SCADA systems.

How Remote Sites Become Prime Targets for Cyber Attack

Remote utility sites, such as offshore wind farms and oil and gas pipelines, are particularly vulnerable to cyber threats. With limited or no access to terrestrial connectivity such as cellular or fiber networks, these remote locations are often the last to receive attention when it comes to cybersecurity. Cybercriminals exploit this vulnerability, targeting sites that lack secure and reliable communications infrastructure. The risk is further compounded by the fact that many utility providers rely on lone workers or contractors to maintain and monitor these remote operations, leaving these sites exposed to cyber threats.

The Role of Satellite Connectivity in Improving Data Security in Utilities

Satellite connectivity has some inherent advantages over cellular networks when it comes to data security; with limited ground infrastructure, it’s less susceptible to physical attacks, and signals are more difficult to intercept. There’s also a reduced risk of infiltration via local Internet Service Providers (ISPs) as these are typically bypassed by satellite communications. But with satellite services diversifying, and more networks being launched, there are now many varying options for data security.

Our Recommended Solution

TSAT is a satellite-based communication system designed specifically for secure, resilient remote monitoring and control of SCADA systems. Unlike traditional ground-based communication networks which can be easily compromised by cyberattacks, the TSAT satellite communication solution provides a more secure and tamper-resistant infrastructure.

TSAT Desktop Version

How TSAT Protects Critical National Infrastructure

The ability to remotely monitor and control systems via satellite communication is essential in maintaining the integrity of critical infrastructure. TSAT’s secure transmission capabilities ensure that communication between central control centers and field sites remains uninterrupted, even in the face of large scale cyber threats.

As mentioned earlier, satellite connectivity has several security advantages over terrestrial networks; a reduced attack surface, plus limited reliance on the public internet to move data being two examples. However, most satellite networks, whether in low earth orbit or geostationary orbit, leverage the internet to move data from the ground station to your application. This process iprotected via VPNs and firewalls, which, in addition to AES-256 encryption of data, satisfies most organizations’ requirements.

Diagram showing how low earth orbit satellites work

Critical National Infrastructure, however, often benefits from, and may even require, complete independence from public infrastructure, and that’s how private satellite networks like TSAT function. Here, as shown in the diagram below, data from the satellite comes to a ground station on your premises, rather than into the satellite network’s ground station. This means that your data is air gapped from external networks.

How private satellite networks work

 

Part of the TSAT service is dedicated satellite bandwidth that prevents interference from other users, ensuring consistent and secure connectivity. TSAT also has no reliance on GPS timing, making it immune to GPS jamming. What’s more, its geo-redundant hubs and frequency diversity allow terminals to automatically switch frequencies if interference occurs, ensuring uninterrupted communication.

Real-World Applications of TSAT

A major energy infrastructure operator connects gas markets between the UK and continental Europe, managing a bi-directional gas pipeline with terminals in two key locations.

To maintain operations, a series of pressure and temperature sensors must continuously transmit data to the company’s SCADA system, which authorizes gas transmission.

If this sensor data becomes unavailable, production must halt, and gas venting procedures are required; an expensive process with significant operational and environmental impact.

To ensure real-time, reliable sensor data transmission, the company requires multiple active communication pathways at all times. They maintain a dedicated fiber connection alongside two satellite connections, all tasked with delivering critical data to the SCADA system. To further reduce reliance on public infrastructure, they have implemented TSAT ground stations at each terminal, eliminating the need for internet-based backhaul.

TSAT-satellite-redundancy

Each satellite link consists of two antennas: a hub and a remote. Typically, the remote antenna is positioned in a more isolated location near the sensors, transmitting data to the hub at the operations center. However, in this case, both satellite dishes are located in close proximity but pointed at different satellites, ensuring redundancy in case of a satellite failure.

Additionally, the company has implemented a unique failsafe: at each terminal, the hub and remote antennas are pointed at opposing satellites relative to the other terminal. This setup provides resilience against localized weather disruptions or signal degradation.

This system has been in place for over 16 years, with hardware upgrades along the way, and in that time, the satellite connectivity has never failed. Ground Control supports the company with a full turnkey service, including setup, training for routine maintenance, and periodic site visits for system health checks.

Embracing Satellite Technology for Cyber Defense

With the growing threats posed by cyber warfare, the time to act is now. TSAT offers a solution that is robust, resilient, and adaptable to the evolving threats of the digital age to utilities. It’s time for utility providers and organizations worldwide to adopt secure satellite enabled technologies, like TSAT, to protect their most vital assets and ensure uninterrupted services to customers. The question isn’t whether you can afford to adopt this technology – it’s whether you can afford not to.

Manufacturing and Heavy Industry operations around the world rely on their machinery to get the job done, efficiently and effectively. The cost of equipment failure and the resulting unplanned downtime has serious consequences for the bottom line, with medium unplanned downtime costs approximately $125,000 per hour. When inflationary pressures, supply chain demands and raw material costs are factored in, unplanned downtime costs for Heavy Industry were calculated as $59 million per year in 2023.

Faced with the need to minimize the business impact of unplanned downtime for critical equipment, industries with heavy assets and significant downtime costs, such as oil & gas and mining, are leading the way in adopting Predictive Maintenance solutions.

By incorporating satellite connected IoT sensors, Heavy Industries operating in remote locations can reliably monitor machinery in real time and react quickly to avoid equipment failures and keep assets operational. The data from satellite-connected sensors on equipment forms a vital component of deploying Predictive Maintenance programs in industries with high asset costs.

What is Predictive Maintenance?

Predictive Maintenance (PdM) is a proactive, data-driven approach that uses advanced technologies – such as condition monitoring, machine learning (ML) and IoT devices – to anticipate equipment failures and schedule maintenance before disruptions occur. By analyzing real-time data from sensors installed on machinery, PdM identifies early signs of wear, faults, or deterioration, enabling timely intervention to prevent costly downtime.

Unlike time-based or reactive maintenance, PdM optimizes equipment performance by triggering maintenance tasks only when specific conditions indicate a need. This approach improves equipment reliability, reduces maintenance expenses, and extends the lifespan of assets. AI-powered analytics and IoT-enabled sensors track key metrics like temperature, pressure or vibration, providing continuous insights into machine performance. When thresholds are exceeded, PdM systems issue alerts or initiate maintenance work orders.

The goal of PdM is to enhance operational efficiency by minimizing unplanned downtime, lowering maintenance costs, and ensuring asset reliability. Industries such as manufacturing, energy, and transportation rely on PdM to align maintenance activities with actual equipment conditions, maximizing productivity and supporting cost-effective, sustainable operations.

Haul Truck Telemetry

What is the Difference between Predictive and Preventive Maintenance?

Although often used interchangeably, Predictive Maintenance (PdM) and Preventive Maintenance (PM) are distinct approaches to equipment upkeep, each suited to different operational needs.

Preventive Maintenance follows a scheduled approach, performing maintenance at regular intervals based on time or measurable usage units, such as engine hours or production cycles. This method ensures equipment is inspected and maintained before issues arise, but it does not consider the actual condition of the asset.

For instance, a Mining operation may replace drill components every six months, regardless of whether those components show signs of wear. While this minimizes the chance of failure, it may result in premature replacements or unnecessary downtime.

Predictive Maintenance leverages real-time data from IoT sensors and advanced analytics to monitor the actual condition of assets. Maintenance is performed only when necessary, based on insights into potential failures or performance degradation.

For example, IoT sensors on a Combine Harvester may detect rising temperatures or irregular vibrations, indicating wear and tear. Predictive maintenance enables technicians to address the issue before a failure occurs, minimizing downtime and repair costs.

Types of Predictive Maintenance

There are three distinct types of Predictive Maintenance: Indirect Failure Prediction, Anomaly Detection, and Remaining Useful Life (RUL). Each approach differs in its desired objectives, the analytical methods used, and the type of information output provided.

Types of Predictive Maintenance

Image adapted from the IoT Analytics Asset Performance & Predictive Maintenance Market Report 2023–2028

Indirect Failure Prediction
Estimates equipment health by calculating a ‘health score’ based on known maintenance requirements, operating conditions and historical performance data. When sufficient data is available, supervised machine learning can be applied to refine the predictions. This approach is scalable since it relies on manufacturer specifications, and it is cost-effective because it uses existing sensors.

Its dependence on large volumes of historical data may render it unsuitable for industries like heavy machinery, where high downtime costs necessitate more immediate and accurate insights.

Anomaly Detection
Identifies potential failures by detecting deviations from normal operating conditions in real time. Unlike methods that require historical data, it relies on current sensor data, making it particularly suited to organizations without extensive machinery usage records. This approach improves predictive accuracy by considering real-time environmental and operational factors rather than predefined maintenance parameters set by the manufacturers.
The risk of false positives can pose challenges, as unnecessary alerts may disrupt operations and complicate machine learning algorithm performance.

Remaining Useful Life (RUL)
Focuses on predicting the time left before equipment failure based on specific machine metrics such as operational hours, distance traveled, or activity cycles. By analyzing sensor data, this method identifies condition indicators that highlight whether the equipment is performing as expected or if faults have accelerated its degradation. RUL models are trained using system data collected under known conditions and applied to predict outcomes under new or variable circumstances.

While this method is highly robust and reliable, it requires detailed, high-quality data for accurate predictions, making it particularly effective for critical equipment in complex environments.

The Benefits of Predictive Maintenance

Predictive Maintenance brings many benefits to organizations through its advanced approach to equipment upkeep, using technology and data analysis to improve asset reliability and efficiency. By identifying potential issues before they lead to failures, PdM helps organizations reduce downtime, optimize resources, and maintain safer working environments.

Research, including findings from the US Department of Energy, highlights the tangible impact of Predictive Maintenance. Compared to preventive maintenance programs, it offers cost savings of 8% to 12%, and when compared to reactive maintenance, cost savings increase to 30% to 40%. These programs also enable a reduction in maintenance costs by 25% to 30% and minimize equipment breakdowns by 70% to 75%.

In addition to cost savings, PdM improves operational efficiency by reducing downtime by 35% to 45% and increasing production capacity by 20% to 25%.

How to Implement Predictive Maintenance

1. Establish Baselines and Data Collection

Baseline performance metrics are identified for the assets by monitoring its condition to set the normal performance benchmarks. Once the baseline is established, sensors are installed to capture real-time data, enabling continuous performance monitoring.

2. Install IoT Sensors on Equipment

IoT sensors are installed on critical equipment to monitor various parameters such as vibration, temperature, pressure, and noise. These sensors continuously collect data on the equipment’s condition and the data gathered is then transmitted to a centralized system for analysis.

3. Data Integration and System Setup

The data collected from the IoT sensors needs to be integrated with the PdM system. This involves connecting the sensors to a computerized maintenance management system (CMMS) or a remote dashboard which allows for real-time monitoring and data analysis.

4. Set Maintenance Thresholds and Automate Alerts

Organizations need to define thresholds for acceptable performance levels. When these thresholds are exceeded, the system automatically triggers maintenance alerts, enabling timely interventions before equipment failure occurs.

5. Select and Implement the Right Analytics Tools

An analytics platform is required to handle the large volumes of data, apply predictive models, and generate actionable insights. Machine learning and AI algorithms are crucial for analyzing sensor data and predicting future equipment failures based on historical data.

6. Develop Predictive Models and Train the System

Predictive models are developed using historical data, maintenance logs and sensor data to forecast future equipment behavior. These models are trained to identify patterns in the data that may signal the onset of failure.

7. Integration with Existing Maintenance Systems

The PdM system is integrated with existing workflows, maintenance management systems, and enterprise resource planning (ERP) systems. This enables seamless communication across platforms and allows for data-driven decision-making.

8. Monitor and Optimize the Program

After implementation, the PdM program should be monitored to evaluate its effectiveness. Continuous data collection and model refinement will help improve prediction accuracy over time.

Industrial Applications of Predictive Maintenance

Predictive Maintenance is becoming increasingly common practice in asset-intensive industries that depend on their large, complex machinery. For industries with assets in remote locations or critical communication requirements, satellite connected IoT devices can transmit real-time sensor data for PdM programs.

Energy and Utilities

The risk of equipment failure in energy production and utilities management can lead to significant financial losses and customer dissatisfaction. Power plants, wind farms, and utility grids employ PdM programs to ensure the continuous operation of critical assets like turbines, generators, and transformers. IoT sensors monitoring parameters such as vibration, temperature, and pressure are used to detect early signs of failure.

By analyzing these data points in real time with advanced predictive models, utility providers can prevent catastrophic failures, optimize energy production, and ensure compliance with regulatory standards. This is particularly important in industries where unexpected downtime can have widespread consequences on both financial performance and customer trust.

Railways and Transportation

PdM is crucial in the transportation industry for ensuring the safety and reliability of infrastructure such as railway tracks, trains, and airport ground equipment. IoT sensors on trains and other critical assets monitor parameters like pressure, temperature, and vibration to detect early signs of wear or failure.

For example, PdM can be used to monitor brake systems or detect track deformations, preventing accidents and service interruptions. By integrating sensors with automated maintenance management systems (CMMS), transportation companies can schedule repairs before a component fails, enhancing passenger safety and reducing operational disruptions.

Oil and Gas

In remote locations such as offshore platforms or desert pipelines, Oil and gas operations face unique challenges in maintaining equipment. PdM is highly beneficial in these situations, as it helps companies remotely monitor the condition of critical machinery like pumps, compressors, and valves.

Satellite-connected IoT sensors track parameters such as pressure, temperature, and vibration to detect signs of imminent failure. Real-time data is sent to cloud-based platforms for analysis, and predictive algorithms generate alerts to maintenance teams, allowing them to address issues before they result in costly downtime or safety hazards.

Mining

With Mining machinery operating in harsh conditions, the risk of unexpected breakdowns can lead to costly delays and safety hazards. Predictive maintenance helps to monitor heavy equipment such as crushers, drills, and loaders, which are critical to mining operations.

Satellite-enabled IoT sensors measure variables like temperature, pressure, and vibration, providing continuous health checks of the machinery. Predictive models analyze these data streams to identify wear patterns and predict when maintenance is required.

Sensor Technologies in Predictive Maintenance

Predictive Maintenance utilizes a range of sensor technologies to monitor the condition of equipment and to detect and address potential failures before they lead to unplanned downtime.

Infrared Thermography

Also known as thermal imaging, infrared cameras identify heat spots which can indicate issues such as friction, electrical resistance, or misalignment in mechanical systems. It is particularly valuable in identifying worn-out components or malfunctioning circuits that tend to overheat.

Infrared thermography allows for real-time monitoring without disrupting machine operation and is frequently used in industries like power generation to track turbine blade conditions and ensure equipment runs efficiently.

Acoustic Monitoring

Using specialized equipment, maintenance personnel can detect ultrasonic or sonic emissions from machinery, which may indicate leaks, electrical discharges, or mechanical wear. Sonic monitoring is typically applied to lower-speed equipment, while ultrasonic analysis is more accurate and applicable to both low- and high-speed machinery.

Ultrasonic analysis is widely used in industries like construction and heavy equipment operations, where hydraulic systems and machinery require constant monitoring to ensure seamless operation and prevent project delays.

Vibration Analysis

Sensors track vibration patterns that help technicians identify potential issues like misalignment, unbalanced components or bearing failures in high-speed rotating equipment, such as motors, drills and fans.

Each machine has a unique vibration signature, and deviations from this pattern can be a strong indicator of mechanical problems. The ability to monitor vibration in real-time allows for early intervention, preventing costly repairs and downtime.

Oil Analysis

By analyzing oil for contaminants, viscosity changes, and particle counts, technicians can pinpoint wear and tear in machine components. Chemical analysis of oil can also reveal overheating or chemical degradation, providing early warnings of issues that could lead to failure.

This technology is often used in heavy industries, such as energy production or oil drilling, where machinery components are subject to extreme operating conditions.

Current and Voltage Sensors

These sensors track electrical characteristics like overloads, short circuits, and failing components. In industries such as mining or energy, where electrical systems are critical, monitoring these parameters ensures safety and minimizes downtime caused by electrical failures.

For example, real-time analysis of electrical data in mining operations can help identify potential issues in equipment like excavators or conveyors, allowing operators to address problems before they cause equipment failure and disrupt production.

Predictive Maintenance and Satellite IoT

For remote operations, such as those found in mining or offshore environments, Satellite IoT becomes a crucial part of the Predictive Maintenance Program. When assets are located in areas with unreliable or no cellular connectivity, traditional IoT solutions relying on cellular networks may fail to transmit vital data. Satellite IoT solutions overcome this challenge by enabling real-time data transmission via satellite, ensuring that assets can be monitored regardless of their location or environment.

Beyond just sensor data collection, Satellite IoT can enable remote control of assets. If an asset is detected to be operating in an unsafe condition, it can be remotely shut down to prevent catastrophic damage or safety incidents. This combination of real-time monitoring and remote intervention significantly enhances worker safety and helps avert equipment breakdowns before they escalate into more serious issues.

The Expanding Satellite IoT Landscape

In recent years, satellite networks have undergone a transformation. Established players have diversified their services, offering greater flexibility and more competitive pricing. At the same time, new satellite constellations are launching at a faster rate than ever, introducing innovative services and standards that promise even more possibilities for IoT applications.

This abundance of options is great news, but it also presents a challenge: with so many variables at play, how do you select the best network for your specific needs? That’s where our expertise comes in. Ground Control has spent over 20 years testing and integrating satellite networks to ensure optimal connectivity for our customers. We’ve distilled our knowledge into an easy-to-follow eBook that covers everything you need to consider.

Key Considerations for Choosing a Satellite Network

When evaluating satellite IoT networks, there are several critical questions to ask:

  • How data-intensive is your application? Understanding your data volume needs is crucial. For instance, message-based services like Iridium Messaging Transport (IMT) are ideal for low-volume, energy-efficient data transmission. On the other hand, IP-based services such as Iridium Certus 100 are better suited for high-data applications like real-time control or video streaming.
  • Where are your sensors located? Coverage matters. While some networks like Iridium offer truly global coverage, others may not reach polar regions or other remote areas. Additionally, factors like terrain and obstructions can affect the choice between Low Earth Orbit (LEO) and Geostationary (GEO) satellites.
  • Is your application stationary or mobile? Mobile applications often require LEO networks, as they don’t rely on precise antenna alignment. Conversely, stationary deployments with a clear line of sight to a GEO satellite may benefit from the stability and cost-effectiveness of GEO-based solutions.
  • How time-critical is your data? Applications requiring real-time data transmission will need well-established LEO networks with IP-based connections. For less time-sensitive use cases, store-and-forward technologies used by some newer LEO networks might be a cost-effective alternative.

Standards-Based vs. Proprietary Networks

One of the most exciting developments in satellite IoT is the emergence of standards-based technologies like LTE Cat 1 and NB-IoT over satellite. These allow a single modem to connect to both cellular and satellite networks, promising cost savings and supplier flexibility. However, these technologies are still in their infancy and come with trade-offs, such as higher power consumption or limited data volumes.

Where you have a combination of relatively high data volumes plus no mains power, proprietary networks offer optimized performance tailored to their specific satellite systems. For instance, message-based protocols like Iridium’s Short Burst Data (SBD) deliver efficient, low-power communication for small data packets, making them ideal for battery-powered IoT devices.

What You’ll Learn in the eBook

Our eBook, How to Choose the Right Satellite IoT Network, dives deeper into these topics and provides actionable insights, including:

  • A detailed comparison of leading satellite networks like Iridium, Viasat, Starlink, and Globalstar.
  • Real-world examples of how different networks excel in specific use cases.
  • A practical framework for evaluating networks based on coverage, latency, power efficiency, and mobility.
  • Insights into emerging technologies and how they may impact your future connectivity strategy.

 

By the end of this guide, you’ll have the tools you need to select a satellite IoT network that aligns with your technical and operational requirements.
