发明名称 PROCEDE ET SYSTEME DE TELECOMMUNICATION PAR SATELLITES DEFILANTS DANS LEQUEL LES COMMUNICATIONS SONT TRANSFERABLES D'UN SATELLITE A UN AUTRE
摘要 The invention concerns a telecommunication method based on moving satellites (S1, S2, S3 and S4) whereby the earth is divided into zones (20i) inside which the communications of the terminals of said zone with the network are relayed by a managing station (22) and a communication terminal (241, 242) and the managing station is provided via a satellite, another satellite taking over the communication when the first satellite is no longer being used. To command the transfer of communications from one satellite to another, predetermined times are selected during which at least two satellites are simultaneously visible from the zone, or from part of the zone. The command for communication transfers is for example collectively carried out for a plurality of terminals.
