摘要
The system is used with a vehicle (V) having an transmitter (E) of e.m. waves and a receiver (R) for the waves returning from a reflector (R') as it passes along the length of a propagation medium (P) of e.m. waves. The Transmitted ( SIGMA e) and reflected ( SIGMA r) waves are compared (C) and a processing module (T) determines the distance between the reflector and the vehicle. The wave emissions and reflections are alternated by sequencers to synchronise the system with a number of positioning devices on vehicles using a transmission network supported by the propagation medium. The sequencers may be placed in the ground and transmit to reflectors the moment when they must be reflecting and to transmitters when they must transmit.
