POSITION DETECTION AND REGISTRATION SYSTEM OF MOBILE TERMINAL EQUIPMENT FOR CIRCULATING SATELLITE COMMUNICATION SYSTEM

摘要

PURPOSE:To provide a system detecting the position of a mobile terminal equipment and registering the position independently of a circulating satellite in the mobile object satellite communication system using the circulating satellite. CONSTITUTION:At least one circulating satellite is arranged to be communicated with a mobile terminal equipment and identification information imparted in advance to each spot beam is transmitted from each circulating satellite. A mobile terminal equipment 1 receives identification information of a spot beam according to a predetermined time interval from a time desiring registration of position. Furthermore, the identification information of the spot beam, the time received respectively and the terminal equipment identification information of the mobile terminal equipment 1 are transmitted. The position of the mobile terminal equipment 1 is estimated and registered based on an area where radiation areas 30-7, 30-7', and 31-3'' of each spot beam are in duplicate at a time when the mobile terminal equipment 1 receives each identification information in a land network 6.
