As an encrypted signal 1000x stronger than GNSS, STL is an ideal solution for augmenting GPS or other GNSS constellations for resiliency and security or as a standalone indoor solution when roof access isn’t an option.
GPS and other GNSS signals play a key role in the operation of critical infrastructure systems such as communications networks, financial systems, power grids, and more. Despite the fact GNSS systems do a good job of providing solutions for diverse applications, they were never designed to be used in many of the ways they are being applied today. And as critical applications push the envelope in their use of GNSS systems, the result is deficiencies which leave them vulnerable.
GNSS signals originate from 20,000 km above the earth and are very weak by the time they reach the ground. This means that they have difficulty working indoors and can be affected by interference ranging from benign sources like ionospheric conditions to more serious ones like intentional jamming. Commercial GNSS signals are also unencrypted, and therefore susceptible to spoofing which is a serious threat for critical applications.
STL, delivered by Satelles, is a secure, robust timing solution that can be used to complement GPS and other GNSS satellite signals, making applications more resilient, reliable, and secure.
Originating from the Iridium® constellation of 66 low-earth-orbiting satellites, STL is 1,000 times stronger than GNSS systems, capable of reaching deep into buildings and overcoming jamming issues without the aid of local infrastructure. Cryptographic security features of STL also provide exceptional resilience to intentional spoofing.
Used in tandem with GPS and other GNSS signals, STL provides a powerful, resilient solution for critical timing applications. Spectracom precision timing products integrated with STL provide the perfect platform for GNSS augmented solutions as well as indoor solutions where GPS can’t be reached. If timing is critical to your application, contact Spectracom to learn more about STL and other Resilient Positioning, Navigation, and Timing solutions.
