[GPS]
Acronym for Global Positioning System. A global satellite navigation system used for determining position, navigation, and time relative to objects on the earth's surface. Orbiting satellites transmit signals that allow a GPS receiver anywhere on earth to calculate its own location through trilateration. Developed and operated by the U.S. government, GPS is used for logistics, mapping, surveying, and other applications that require precise positioning; it is part of the international GNSS constellations spread between several orbital planes.
