Sense: noun/1
GPS (Global Positioning System) is the specific name of the US satellite-based navigation system, but in everyday English it has become a generic term for any satellite positioning technology. 'Satellite navigation' (or 'sat nav' in British English) is a broader category that includes GPS as well as other systems like Russia's GLONASS or Europe's Galileo. 'Satellite navigation' sounds more formal and is common in technical writing, while 'GPS' is used freely in casual speech and product names. 'Navigation system' is the most general — it could refer to map-based, inertial, or radio-based systems that do not involve satellites at all. For example: 'The car's GPS suggested a faster route' (specific technology), but 'The aircraft uses an inertial navigation system when satellite signals are unavailable' (different technology entirely).

Etymology
GPS is an acronym for 'Global Positioning System', a satellite-based navigation system developed by the United States Department of Defense. The system was first proposed in the 1960s, with the first satellite launched in 1978, and it became fully operational in 1995. The name was chosen because the system provides positioning information anywhere on the globe, at any time. Over time, 'GPS' has become a generic term for any satellite navigation technology in everyday language.
