What is the difference between GNSS and GPS?

4 March 2021

GNSS stands for Global Navigation Satellite System. This is an umbrella term that covers all global satellite positioning systems including GPS (Global Positioning System) a constellation of satellites developed by the United States Department of Defence originally for military use but now available for commercial and consumer use.
The main difference between the two is that GNSS systems provide increased accuracy and reliability because they can use satellites from other networks beyond the GPS system, for example GLONASS (Russian), EGNOS (European), Galileo (European) and Beidou (Chinese).
GNSS-compatible equipment can use navigational satellites from other networks beyond the GPS system, and more satellites means increased receiver accuracy and reliability. All GNSS receivers are compatible with GPS, but GPS receivers are not necessarily compatible with GNSS. The most advanced instrument in KOREC’s range is the Trimble R12i whilst the Trimble R1 is more basic, pocket sized receiver.
