ABSTRACT:
An SS-TDMA satellite system providing uplink and downlink interconnections through an on-board microwave switching matrix controlled by an on-board distribution control unit responsive to ground command signals. The distribution control unit is configured to permit both point-to-point and point-to-multipoint interconnections of uplinks to downlinks through the switching matrix. Point-to-point interconnections under system static mode control may be effected simultaneously with point-to-point interconnections under system dynamic mode control.
