SATELLITE COMMUNICATION SYSTEM, GATEWAY, SATELLITE REPEATER, COMMUNICATION NETWORK CONTROL STATION, AND SATELLITE COMMUNICATION METHOD

摘要

In a satellite communication system to relay communication between a terminal (502) and a gateway (505) installed on the ground through a satellite repeater (503), the satellite repeater (503) forms a user link beam for communicating with the terminal (502) and a feeder link beam for communicating with the gateway (505) in a same area, and changes frequency or polarization association with respect to each of the user link beam and the feeder link beam, based on a traffic situation. Thus, a capacity that can be communicated by the beam may be changed after satellite launching.
