Abstract

La présente invention se rapporte à un procédé de basculement du trafic dans un système de communications par satellites en orbite basse à destination de terminaux, la connection d'un terminal à un réseau terrestre de communication étant accomplie au moyen d'une station de connection. Le basculement des liaisons satellite-terminal et satellite-station de connection n'est possible qu'à l'intérieur d'une zone déterminée. La décision de basculer le trafic est prise en fonction de la dégradation de la qualité de service et de l'environnement radioélectrique sur un groupe de terminaux de ladite zone. L'invention concerne également des équipements destinés à la mise en oeuvre de ce procédé notamment des terminaux émission/réception, ainsi que des stations terrestres d'interconnexion. La présente invention peut être appliquée notamment au domaine spatial.
