What is GPS?

GPS stands for the Global Positioning System. It can tell you precise location anywhere on the Earth to within 6 metres. A group of 24 or more satellites orbit the Earth at an altitude of 11,000 miles. Every 12 hours, a satellite makes an orbit or one complete cycle in space around the Earth. The satellites transmit signals to receivers on the ground. The user has a GPS receiver which detects the signals from the satellites and calculates their distance from the receiver. Receivers can be held in your hand or mounted in a vehicle, such as a car or a ship. A hand-held receiver is about the size of a mobile phone, but the newer models are even smaller.
