GNSS (Global Navigation Satellite System) is the collective name for global navigation satellite systems, and GPS (Global Positioning System) is one of the specific implementation systems.

Specifically, GPS is a satellite navigation system jointly developed and operated by the National Aeronautics and Space Administration (NASA) and the U.S. Department of Defense (DoD). It was originally composed of 24 navigation satellites and is used around the world. Positioning and navigation. Because GPS is the earliest established and widely used navigation system, the term "GPS" is used to refer to the global navigation satellite system on many occasions.

GNSS is a broader term used to describe satellite navigation systems established and operated by multiple countries and regions. In addition to GPS, there are also Russia's GLONASS, Europe's Galileo, China's Beidou navigation system, etc. These systems are complementary and compatible with each other, providing positioning and navigation services worldwide.

Therefore, GPS can be regarded as a subsystem of GNSS, and GNSS is a general term that includes multiple navigation satellite systems. Their main differences lie in operating countries, system architecture, signal characteristics, etc., but their goal is to provide global positioning and navigation services.
