A recent report from Weekly Intelligence Summary from Digital Shadows, a cybersecurity monitoring service, indicated jamming, blocking, or spoofing of GNSS signals by the Russian government is “more indiscriminate and persistent, larger in scope, and more geographically diverse than previous public reporting suggested.

This is important because all critical national infrastructures rely on GNSS for time and location synchronization; GNSS is vulnerable to Russian interference tactics.

Additionally, Russians have started hacking into the global navigation satellite system on a mass scale to confuse thousands of ships and airplanes about where they are,a study of false GNSS signals by C4ADS found.

Satelles STL service delivers a solution for global time and location that is completely independent from GPS, and is available today. Originating from the Iridium® constellation of 66 low-earth-orbiting satellites, Satellite Time and Location (STL) is 1000 times stronger than GPS, reaching deep into buildings and penetrating GPS jamming without the aid of local infrastructure. Cryptographic security features of STL also provide exceptional resilience to intentional spoofing. STL perfectly augments GPS and other location-based technologies, and provides the absolute height of security.
