    Abstract
    Traffic estimates for the next generation of commercial communications satellites strongly indicate the desirability of using highly directive multibeam antennas to increase channel capacity. This antenna configuration allows multiple access via space division and frequency sharing through the isolation inherent in the directive multibeam antenna. Coupling this technique with a satellite-borne programmable communications distribution subsystem results in a highly efficient system. The distribution subsystem, consisting of a distribution control unit (DCU) and microwave switch matrix (MSM), is introduced into the satellite communications equipment prior to the output amplifiers and enables interconnection between all earth terminals accessing the satellite. Data on the traffic flow allocation required to provide service is stored in an onboard memory and is used to directly control MSM operation.. Flexibility to adapt to changes in traffic flow patterns is achieved through ground command of the onboard memory contents. A detailed description of the DCU and a general discussion of the space segment are provided.
