The ability to track the whereabouts of a person, vehicle or object has been around since 1973 when the first ideas of GPS were discussed. The idea of the GPS project was to establish a system that did not suffer the problems associated with traditional navigation systems of the day.
The basis of the world's current car dvd system relied on a receiver being able to make contact with at least four satellites at any one time and by 1994 the US Department of Defence had established 24 satellites in orbit to achieve this aim. The Russian Military had its own "Global Navigation Satellite System", which became available to civilians in 2007, and there is also the European "Galileo Positioning System" and the Chinese "Compass Navigation System."
