The full name of GPS is Global Positioning System.
The Global Positioning System (GPS) is a satellite-based radionavigation system owned by the United States government and operated by the United States Space Force. It is a global navigation satellite system (GNSS) that provides geolocation and time information to a GPS receiver anywhere on or near the Earth where there is an unobstructed line of sight to four or more GPS satellites. GPS does not require the user to transmit any data, and it operates independently of any telephonic or internet reception, though these technologies can enhance the usefulness of the GPS positioning information. It is used for numerous applications including navigation, surveying, agriculture, and timing.
The system was initially developed for military use but was made available for civilian use in the 1980s. Since then, GPS has become an integral part of daily life, enabling a wide range of applications and services, from turn-by-turn navigation in cars to precision timing in financial markets.
