Beschreibung
Zusammenfassung:	The invention concerns a system for the remote sensing of the position of a moving vehicle, comprising a transceiver on board of the moving vehicle and a remote receiver. The transceiver receives GPS signals which it re-transmits at a different frequency to the receiver. This device comprises a modulator (22) modulating in frequency, in amplitude or in phase the received signals on a carrier with frequency independent of the speed and position determination. The moving vehicle transmission to the receiver is carried out at this carrier frequency. Preferably, a frequency transposing circuit (14) is arranged upstream of the modulator (22) to lower the frequency of the signals received from the satellites or beacons.
