Global Positioning System. Artwork of the orbits of the Navstar satellites used in the Global Positioning System (GPS). The GPS system uses a constellation of 24 operational Navstar satellites in 6 orbital planes,ensuring that 3-6 satellites are above the horizon at any location at any one time. Small ground-based receivers calculate the user's position by measuring the time it takes for signals to arrive from the satellites. Military receivers have an accuracy of a few metres,whilst the degraded signals intended for civilian use give an accuracy of less than 100 metres | |
