Signals are detected in a single receiving channel (1 - 4). The time difference between the reception of signals emitted by the transmitting stations of two different units are measured by detecting and measuring the signals emitted by the stations of one unit during the predetermined period of time specific to this unit and by detecting and measuring the signals from the transmitting stations of ...
