Satellite transmission antenna beam pattern and signal call connection method in low-earth orbit satellite communication system

摘要

The present invention relates to a personal (cellular) communication system using a low-orbit satellite, and more particularly, to a satellite communication system in which a low-orbit satellite communication system, The present invention relates to a beam pattern of an antenna and a call connection method thereof. In the low-orbit satellite system, a transmission antenna beam pattern of each satellite is increased by increasing the electric field intensity of a transmission signal transmitted to a peripheral portion of a service region, The strength of the transmission signal transmitted to the periphery of the service area opposite to the traveling direction of the service area is lowered and when the terminal requests the handoff, the strength of the most received power among the plurality of satellites, By selecting a large satellite, the service area stay time is maximized There is an effect that makes connection and satellite.
