Our S-GNSS® product is the only consumer grade software product capable of determining the angle of arrival of GNSS signals, enabling rejection of spoof signals and spoofer localisation.
This effectively provides military-grade spoofer rejection and localisation through software alone, on consumer-grade devices.
- New category of angle of arrival measurements
- 25x improvement in receiver sensitivity
- Detection and rejection of signal spoofing
- Determination of the physical location of signal spoofers
How it works
Spoofing involves broadcasting fake satellite signals in order to confuse the receiver. Spoofing is used by criminal networks, maritime pirates and fraudsters. As the cost of spoofing technology comes down, the danger to business and consumers is increasing.
Supercorrelation is the underlying technology inside S-GNSS. Supercorrelation enables a receiver to determine the direction each signal is coming from, meaning it can instantly detect fake signals as spoofers and ignore those signals completely. It can also pinpoint where in the physical environment the signal is coming from.
S-GNSS is the only consumer-grade product in the market capable of these unique performance characteristics.
The closest existing alternative is a military-grade Controlled-Radiation Pattern Antenna (CRPA) which uses 7 antennas mounted within a large dome in order to ignore spoofers. A CRPA is typically $10,000, weighs 7.5kg, and consumes 20W.
S-GNSS can improve the sensitivity of receivers by up to 25x using just software, currently such gains are only possible by adding expensive hardware antennas.
