METHOD FOR LOCATING VEHICLES

A method for locating surface vehicles, particularly in a city area, in which the vehicle to be located transmits a measuring radio signal which is received by at least three differently located radio receiving stations, with the signal values received at each station being conducted, in suitable form, over fixed lines to a central station at which the transit time differences of the measuring signal on its path towards two different receiving stations are determined by means of a phase comparison, with transit time fluctuations occurring in the receiving and transmission devices being compensated by additionally obtained correction values, for example, derived from signals received by the respective receiving stations from a fixed location with known distances from such receiving stations, and evaluating at least two such independent difference values for the determination of the location of the vehicle.
