Abstract:
1. A communication satellite facility comprising a first satellite at least having a receiving antenna adapted to receive radio-frequency signals transmitted from a ground station, down converter means adapted to convert the radio-frequency signals received by said receiving antenna to intermediate frequency signals, a transmitting antenna adapted to transmit radio-frequency signals to the ground station, up converter means adapted to the intermediate frequency signals to be transmitted again to the radio-frequency signals, switching means adapted for switching/routing the transmitted/received radio-frequency signals and wideband intersatellite communication means adapted for bidirectional wideband intersatellite communication between said first satellite and a second satellite; and said second satellite at least having wideband intersatellite communication means adapted for bidirectional wideband intersatellite communication between said second satellite and said first satellite, modulating/demodulating means adapted to modulate/demodulate the signals transmitted and received by said wideband intersatellite communication means, and a circuit switching unit for a data link layer and a network layer to conduct baseband signal processing.
