A GPS navigation device or GPS receiver , and when used for vehicle navigation commonly referred to simply as a GPS , is a device that is capable of receiving information from GPS satellites and then to accurately calculate its geographical location. The Global Positioning System (GPS) is a global navigation satellite system (GNSS) made up of a network of a minimum of 24, but currently 30, satellites placed into orbit by the U.S. Department of Defense . [1]

The GPS was originally developed for use by the United States military, but in the 1980s, the United States government allowed the system to be used for civilian purposes. Though the GPS satellite data is free and works anywhere in the world, the GPS device and the associated software must be bought or rented.

The Russian Global Navigation Satellite System ( GLONASS ) was developed contemporaneously with GPS, but suffered from incomplete coverage of the globe until the mid-2000s. [3] GLONASS can be added to GPS devices which makes more satellites available and enabling positions to be fixed more quickly and accurately, to within 2 meters . [4]
