The American GPS constellation, comprising 31 satellites, pioneered this technology, but it's no longer alone. Today's smartphones and smartwatches typically support multiple GNSS constellations: ...

Original Open Source GPS/GNSS SDR Original Open Source GPS/GNSS SDR This is the effort which opened GPS/GNSS receiver architectures to all. Many are using this code and actively use the original SiGe ...

GPS and its GNSS (Global Navigation Satellite System) counterparts — Europe’s Galileo, Russia’s GLONASS and China’s Beidou — play a vital role in myriad economic activities.

Pyramid GNSS was running on a Linux-powered laptop with GPS receiver and successfully intercepted spoofed GNSS signals coming from another laptop with a software-defined radio a few feet away.

Targeting GPS Given how dependent aviation systems have become on positioning data, it was only a matter of time before military combatants began targeting GPS/GNSS to disrupt enemy aircraft.

Realistically, there is no singular solution to replace GPS, but we can make it more resilient with complementary AltPNT technologies.

Jamming and spoofing interferes with Global Navigation Satellite Systems (GNSS), of which GPS is a vital one used by transportation authorities, industry, and billions of people every day.

Also, Johan had included two GPS drivers in his patch, indicating that even though his subsystem might not contain GNSS-specific code, it was still useful for its intended purpose—regularizing the GPS ...
