A method for monitoring vehicles from a central station, consisting of obtaining the approximate coordinates of each vehicle from signals transmitted by stations of the world omega network and using a vehicle-carried receiver. These approximate coordinates are corrected by reception and processing means, connected to fixed radiogoniometry beacons. Processing means connected to the vehicle-carried receiver supply the real coordinates of the vehicle to a vehicle-carried transmitter, the real coordinates being transmitted in coded form to a receiver of the central station. A bilateral sound communication between the station and the vehicles can be conducted by the communication means. Alarms on board vehicles can be transmitted to the station.
