GPS and Applications

The Global Positioning System, usually called GPS (the US military refers to it as NAVSTAR), is an intermediate circular orbit (ICO) satellite navigation system used for determining one's precise location and providing a highly accurate time reference almost anywhere on Earth or in Earth orbit.The GPS space segment uses a total of 24 satellites in a constellation of six orbiting planes. This configuration provides for at least four equally- spaced satellites within each of the six orbital planes.
