Ground Control has launched the RockBLOCK Pro, the first certified Iridium Certus 9704 device available through an Iridium partner. This rugged satellite IoT gateway utilizes the new Iridium Certus® 9704 module and Iridium Messaging Transport (IMT). The RockBLOCK Pro delivers enhanced performance compared to earlier RockBLOCK versions, and features faster speeds, substantially increased message size capabilities, and improved power efficiency. This makes it well-suited for critical remote operations.
RockBLOCK Pro utilizes the Iridium 9704 module to send bi-directional messages from 25 bytes up to 100 KB, supporting aggregated sensor data, imagery and audio clips while maintaining end-to-cloud latency under 10 seconds. Compared to the Iridium 9602 and 9603 modules, the 9704 achieves up to an 83% reduction in idle power consumption, making it the most power-efficient Iridium module ever.
Engineered for harsh outdoor and industrial use, RockBLOCK Pro is rated IP66 and can be specified with either the built-in high-gain antenna or an external antenna. Full support for the legacy Iridium AT command set ensures a drop-in upgrade path for existing SBD deployments, with no need to alter host firmware or development toolchains.

For seamless end-to-end messaging, RockBLOCK Pro integrates tightly with our Cloudloop Data platform, which delivers messages via direct cloud-platform integrations, including AWS, Azure and Google Cloud environment, or can be routed via HTTP webhooks, MQTT streams, or even email. Onboard GNSS, Bluetooth, and configurable digital I/O further expand its utility in telemetry, asset tracking, environmental monitoring, and autonomous applications.
Alastair MacLeod, CEO of Ground Control, said: “RockBLOCK Pro redefines the satellite IoT gateway category by bringing together power efficiency, rugged design, and data capacity in a compact footprint, unlocking smarter, more responsive systems in the world’s most remote places. As the first partner to bring a certified Iridium Certus 9704 product to market, we’re proud to lead the next chapter of global IoT.”
“The Iridium Certus 9704 packs a lot of power in a compact module, making it ideal for IoT applications that require real-time data analysis, analytics and automated decision-making,” said Tim Last, executive vice president of sales and marketing, Iridium. “Ground Control has been a trusted Iridium partner for many years, with a proven track record of delivering high quality developer hardware built on Iridium technology. We’re excited to see them leading the way with innovative solutions that bring high performance satellite IoT connectivity to the most remote parts of the world.”
