Abstract

Dispositif d'interconnexion pour réseaux à satellite et terrestres. Le dispositif comprend le maintien des niveaux de puissance des transmissions en réseau terrestre reçus par les abonnés à environ un ordre de grandeur supérieur à ceux des transmissions par satellite dans le même canal, afin de surmonter les perturbations et de maintenir les transmissions des abonnés à des réseaux terrestres à des niveaux de puissance d'environ un ordre de grandeur inférieur aux transmissions dans le même canal destinées aux réseaxx à satellite, ceci pour éviter de provoquer des perturbations au niveau du satellite. On réalise ce maintien des niveaux de puissance à l'aide du réseau qui se trouve en communication avec l'abonné. Par ailleurs, un satelite qui n'est pas sur orbite sert de n÷ud de commutation entre à la fois le réseau satellite et un réseau terrestsre pour relayer des informations entre un abonné terrestre et le réseau radiotéléphonique à satellite par l'intermédiaire d'un réseau terrestre. Ce réseau terrestre et le réseau à satellite peuvent communiquer l'un avec l'autre soit par l'intermédiaire du spectre intersatellite soit par celui du spectre Terre/Satellite.
