What is the difference between gnss and gps

The difference between gnss and gps is very big, because GNSS (global navigation satellite system) and GPS (global positioning system) are two related but not identical concepts. GNSS is a broad concept that covers It refers to multiple satellite navigation systems developed and operated by various countries and regions around the world, while GPS refers solely to the satellite navigation system developed and operated by the U.S. government.

GNSS (Global Navigation Satellite System) and GPS (Global Positioning System) are two related but not identical concepts.

GPS is a satellite navigation system developed and operated by the U.S. government. It includes a group of satellites maintained in orbit as well as control stations and user receiving equipment on the ground. The GPS system is mainly used to provide global positioning and navigation services.

GNSS is a broader concept, which covers multiple satellite navigation systems developed and operated by various countries and regions around the world, including GPS (United States), GLONASS (Russia), Galileo (Europe), BeiDou (China) et al. The GNSS system integrates multiple satellite navigation systems to provide more comprehensive and reliable global navigation and positioning capabilities.

Therefore, GPS is a member of the GNSS system, and GNSS is a larger concept that refers to multiple satellite navigation systems around the world. Functionally speaking, GPS is used for specific global positioning and navigation services, while GNSS is a more comprehensive and general term that covers the overall capabilities of multiple systems.

It should be noted that although the GNSS system includes satellite navigation systems from many different countries and regions, they may have some technical differences, such as differences in signal frequency, positioning accuracy, etc. Therefore, in actual use, a suitable satellite navigation system needs to be selected based on specific needs and availability.
