Abstract
A method for geolocating a terminal of a wireless communication system from measurements of a parameter representative of a radio signal exchanged between the terminal and base stations of the communication system. The method uses fixed base stations and a mobile base station which is displaced in a determined search area. During a predefined search period, the terminal emits several radio signals to the fixed base stations and the mobile base station. A precise geographical position can then be determined, on the one hand, from the measurements carried out during the search period for the different base stations, and on the other hand, from the geographical positions of the fixed base stations and from the geographical positions of the mobile base station at the different times of emission of the radio signals by the terminal.
