Abstract
A system for identifying the location of an aircraft on the surface of an airport includes a plurality of low power FM transmitters located along the boundaries of runway and taxiways. Each transmitter provides an FM signal having a common carrier frequency and each FM signal is encoded with unique information indicative of the position of the transmitter on the airport surface. Aircraft and other vehicles containing a conventional FM receiver 'capture' only the strongest signal and process the 'captured' signal to determine which transmitter was the source of the signal and hence where the aircraft is on the airport surface.
