Abstract

Procédé et système de localisation d'un émetteur radiofréquence. Un procédé de localisation d'un émetteur radiofréquence (12) à bord d'une station mobile (14) comprend l'émission, par l'émetteur, d'un signal radiofréquence (20) portant une information d'horodatage d'émission par rapport à une horloge embarquée, la réception du signal (20) par des stations de réception (161, 162, ..., 1 6i, ..., 16N) synchronisées, l'horodatage de la réception du signal par chacune des stations, la détermination, par chaque station (16i), d'une pseudo-distance entre l'émetteur (12) et la station (1 6i) sur base des informations d'horodatage d'émission et de réception, la mise à disposition, par les stations, des pseudo-distances à un centre de calcul (18), et le suivi, par le centre de calcul (18), de la position de l'émetteur (12) sur base des pseudo-distances. Un autre aspect de l'invention concerne le système de localisation. L'invention sera d'intérêt pour la localisation de stations mobiles de tout type.Method and system for locating a radiofrequency transmitter. A method of locating a radiofrequency transmitter (12) on board a mobile station (14) comprises the transmission, by the transmitter, of a radiofrequency signal (20) carrying transmission timestamp information by compared to an on-board clock, the reception of the signal (20) by reception stations (161, 162, ..., 1 6i, ..., 16N) synchronized, the time stamp of the reception of the signal by each of the stations , the determination, by each station (16i), of a pseudo-distance between the transmitter (12) and the station (16i) on the basis of transmission and reception timestamp information, the provision, by the stations, pseudo-distances to a computer center (18), and the monitoring, by the computer center (18), of the position of the transmitter (12) on the basis of the pseudo-distances. Another aspect of the invention relates to the location system. The invention will be of interest for the location of mobile stations of all types.
