GPS
GPS stands for Global Positioning System and is used primarily to locate features on the earth. The system is a constellation of between 24 and 32 medium earth orbit NAVSTAR satellites that transmit precise radiowave signals that enable GPS receivers to determine their current location, time, and velocity (including direction), anywhere on earth.
GPS NAVIGATION
This is the utilization of GPS technology to assist in the arrival at a final destination from an initial location. Timely, automatic instructions are issued via map illustrations, text, and voice commands, offering the user turn by turn directions to a desired destination.
