1. Here is an illustration of a typical GPS satellite. It has solar panels to use solar energy to powers its electrical systems. It has a many antennas to communicate with other GPS satellites and ground stations Global Positioning System: GPS Satellite

2. Global Positioning System: Orbits of GPS Satellites This illustration shows a general overview of the GPS Satellites and their orbits. In total there are 24 operational GPS satellites orbiting earth.

3. Global Positioning System: Positioning The GPS satellites are divided into 6 planes each plane containing 4 satellites. The GPS satellites used the method of triangulation. This means that readings are taken from at least three satellites to better accuracy in terms of global positioning of a person or an object.

4. Global Positioning System: Ground Terminals Finally the satellites relay the information to a ground station that in turn relays the information to the devices such as the navigation systems. Some navigation devices have the capability of obtaining the information directly from the satellite.
