A satellite-based communications system operating at high data rates includes a plurality of communications satellites each having an uplink and a downlink antenna for receiving and transmitting a plurality of spot beams corresponding to a plurality of coverage areas at a plurality of frequencies. The system further includes a plurality of dedicated communications links between a source location in one of the plurality of coverage areas and a destination location in another one of the plurality of coverage areas wherein the plurality of dedicated communications links are each assigned an exclusive time interval for transmitting and receiving communications signals to and from each of the plurality of satellites. The plurality of satellites each have an uplink and downlink antenna beam switch coupled to the uplink and downlink antennas for selecting a reconfigurable subset of the plurality of spot beams based on the time interval. The plurality of satellites each further have a primary communication payload for receiving and transmitting signals at a primary range of frequencies in each of the plurality of spot beams and a secondary communication payload for receiving and transmitting signals at a secondary range of frequencies in each of the plurality of spot beams upon occurring a drop-out of the primary communication payload. The system further includes a plurality of user terminals having a primary communication antenna for transmitting and receiving signals to and from each of the plurality of satellites at the primary range of frequencies.
A system for providing high frequency data communications in a satellite-based communications network, the system comprising:
In a satellite-based communications network including a plurality of communications satellites (12) each having uplink and downlink antennas (38,44) capable of receiving and transmitting a plurality of signals utilizing spot beams to a plurality of coverage areas (43), the plurality of satellites (12) each further having uplink and downlink antenna beam switches (39,41) coupled to the uplink and downlink antennas (38,44) respectively for selecting a reconfigurable subset of the plurality of coverage areas (43) so as to provide satellite communications to a subset of the plurality of coverage areas (43), the network further including a plurality of dedicated communications links between a source location in one of the plurality of coverage areas (43) and a destination location in another one of the plurality of coverage areas (43) and a plurality of user terminals (16) for transmitting and receiving signals to and from each of the plurality of satellites (12) utilizing one of the plurality of dedicated communications links, a method for providing high frequency data communications, the method comprising:
