Global Positioning System
Similar Terms: GPS,gps
GPS is a >Satellite Navigation system used to determine ground position and velocity (location, speed, and direction).
Â
It is made possible by a "constellation" of 24 satellites that orbit the Earth, continually transmitting their changing position with time. The spatial distributon of the satellites allow ground receivers to continually be in contact with 4 satellites, allowing the receivers to collect this data and triangulate their own position to pinpoint their geographic location.
Â
The location accuracy is anywhere from 100 to 10 meters for most equipment and can be improved by using the >Wide Area Augmentation System (WAAS) or Differential GPS (DGPS).
Â
The GPS is owned and operated by the U.S. Department of Defense but is available for general use around the world.
