SATELLITE COMMUNICATION METHOD AND SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a satellite communication method and system capable of compensating performance deterioration in a satellite communication line to improve line performance. SOLUTION: In a satellite communication system which has a base station, a user station on the ground and a plurality of satellite stations and performs communication via the satellite stations, one uplink signal is simultaneously transmitted from the user station having directivity with which the plurality of satellite stations are covered toward the plurality of satellite stations, the uplink signal is converted into feeder link signals, respectively and transmitted to the base station by each feeder link in each satellite station which receives the uplink signal and in-phase composition is performed to each received signal after adjusting each received signal to in-phase in the base station which receives each feeder link signal.
