The Global Positioning System (GPS) is a satellite-based navigation system 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. Originally developed for military use, GPS has become an essential tool for various civilian applications, including navigation, mapping, and timing services.
