Abstract

Procédé anti-géolocalisation d’un premier terminal de télécommunication par satellite, dispositif et programme d’ordinateur associés Procédé anti-géolocalisation d’un premier terminal de télécommunication par satellite (20), comprenant les étapes suivantes mises en œuvre par un module électronique (21) d’émission du premier terminal : - mise en forme, par un algorithme de traitement du signal, d’un signal satellite ; - émission via l’antenne satellite (24) du premier terminal, dudit signal satellite mis en forme, à destination d’un deuxième terminal de télécommunication satellite (30) sur une liaison de télécommunication satellite (3, 4) via un satellite défilant (10) ; l’algorithme de traitement du signal comprenant au moins une opération de masquage des caractéristiques, indiquant la position du premier terminal satellite, de la fréquence Doppler. Figure pour l'abrégé : Figure 1Anti-geolocation method of a first satellite telecommunications terminal, associated device and computer program Anti-geolocation method of a first satellite telecommunications terminal (20), comprising the following steps implemented by an electronic module ( 21) transmission from the first terminal: - shaping, by a signal processing algorithm, of a satellite signal; - transmission via the satellite antenna (24) of the first terminal, said shaped satellite signal, to a second satellite telecommunications terminal (30) on a satellite telecommunications link (3, 4) via a traveling satellite ( 10); the signal processing algorithm comprising at least one feature masking operation, indicating the position of the first satellite terminal, of the Doppler frequency.
