Reliable Location Tracking Without GPS
In conflict zones and contested environments, GPS isn’t guaranteed. Adversaries know how to jam or spoof traditional positioning systems, putting your personnel and missions at risk. RockSTAR STL gives you a new level of resilience with location data that doesn’t rely on GNSS systems. Instead, it uses STL: a one-way, encrypted signal, broadcast at 1,000 times the strength of GPS, by Iridium’s satellite constellation.
This means your position is calculated securely and independently of GPS. Even in environments where GPS signals are blocked, degraded, or spoofed, you still get reliable PNT (Positioning, Navigation, and Timing) data, critical for mission success, situational awareness, and personnel safety.


A New Standard for Mission Critical Tracking
With global satellite messaging capabilities, users can send and receive messages, access mission critical information, and activate emergency alerts from even the most remote or high risk locations. Whether it’s for navigation, real time tracking, or emergency communication, RockSTAR STL delivers reliable connectivity, backed by Iridium’s trusted and 100% global satellite network.
The device’s compact, rugged form factor makes it suitable for use in challenging environments – extreme weather, military conflict zones, or disaster areas. The combination of satellite tracking and STL-based location data ensures seamless, uninterrupted service for mission critical applications.
