Global Positioning System (GPS)

A worldwide radio-navigation system formed from a matrix of satellites and their ground stations. GPS is funded by and controlled by the U.S. Department of Defense (DOD). While there are many thousands of civil users of GPS worldwide, the system was designed for and is operated by the U. S. military. GPS provides specially coded satellite signals that can be processed by a GPS receiver, enabling the receiver to compute position, velocity and time.
