Global Positioning System (GPS) is a set of satellite-based navigation systems that allow users to determine their exact location and provide accurate navigation information. There are several synonyms for the term GPS, including Global Navigation Satellite System (GNSS), Satellite Navigation System, and Positioning System. While these synonyms essentially refer to the same technology, some of them may be more region-specific or associated with particular manufacturers or agencies. For instance, the European equivalent to GPS is Galileo, which is operated by the European Space Agency and provides similar services to GPS. Regardless of the term used, GPS technology has become an integral part of modern navigation, with applications ranging from aviation and maritime transport to personal navigation and location-based services.
