GPS Navigation Systems
GPS stands for Global Positioning Systems. It was originally developed by the US Department of Defence as an aid for navigation using Global Satellite Systems.A series of satellites (between 24 and 32 in number) are used for this purpose. These satellites transmit radiowave signals which are received by the GPS receivers on earth (or on air or in water).
This enables the GPS receivers to compute their time, location and velocity precisely, aiding in their navigation. The GPS systems became fully operational in 1993. It is now a key tool for aiding navigation globally and an essential tool for activities such as land surveying, mapping, tele-coomunications and commerce.
