Device and method for positioning and controlling railway vehicles with ultra-large bandwidth

A device for positioning and controlling rail vehicles (4) comprising:

• fixed stations (1) comprising a first signal transmitter and receiver (2);
• and
• a central control station (3) to which are connected the fixed stations (1) and controlling a transport zone,
• wherein,
• each rail vehicle (4) comprises second signal transmitter and receiver (6) containing a specific identifier of a transmitter and at least one message,
• the signals transmitted by the first transmitter and receiver (2) of the fixed stations (1) contain a specific identifier of the transmitter and at least one message,
• the central control station (3) sends rail operation control orders,
• each rail vehicle (4) and each fixed station (1) include processor (8) for determining the identifier and at least said message of each signal received,
• the signals of the first and second transmitter and receiver (2, 6) are non-sinewave radio signals with a very large passband whereof a frequency spectrum ranges between 1 and 10 GHz.
