GPS AND TRIANGULATION GPS calculation works on the principle of the receiver (example the handheld GPS receiver on car or mobile) calculating the distance of that receiver from a set of known points. 1) The receiver needs to receive a straight line signal (also called line of sight) from the known point without reflection. The best things that can do that are satellites overhead. 2) To enable that‚ the US department of defence has setup 24 low earth orbit (LEO) satellites. They are called the
