摘要
The system for locating a railway vehicle (V) in relation to a fixed wave propagating rail (P) includes a circuit (E) placed on the vehicle and transmitting electromagnetic waves (Ee). The waves are reflected (Er) at a fixed position (R') in the rail and received (R) on board of the vehicle. A comparison circuit (C) compares the transmitted waves with the reflected waves. A processing circuit analyses the difference between the two signals in order to determine the distance travelled by the reflected wave, and hence the distance of the vehicle from the fixed reflector position.
