A method for geolocating a terminal of a wireless communication system. A set of reference elements is determined with the aid of messages transmitted by calibration terminals during a calibration phase. Each reference element includes a radio signature and a geographical position of a calibration terminal when a message is transmitted. A refinement phase makes it possible to clean and/or to enrich the set of reference elements by virtue of the identification of points of interest corresponding to preferential positions of transmission of messages by the terminals. During a search phase, the position of a terminal of interest is determined based on its radio signature and of the modified set of reference elements.
