GPS or Global Positioning System (GPS) is a satellite-based system owned and MAINTAINED by USA Govt. It is an all-weather system, used to provide locations and time information anywhere in the world.A simple example is GPS receiver installed in radio cabs. GPS can provide real time 3D positioning, navigation and timing anywhere on or NEAR the earth. GPS system is used extensively by military, commercial and civil users worldwide.

Working: The GPS concept is based on time. The SATELLITES carry very stable atomic CLOCKS that are synchronized to each other and to GROUND clocks. GPS satellites continuously transmit their current time and position. A GPS receiver monitors multiple satellites and solves equations to determine the exact position of the receiver and its deviation from true time.
