1. A telecommunications satellite payload processing system comprising one or more identical generic integrated processor modules, wherein the number of integrated processor modules is selected in accordance with the antenna and bandwidth characteristics of a specified mission uplink and downlink in relation to characteristics of the integrated processor module and wherein each integrated processor module contains a digital processing stage comprising:

  • a plurality of input ports adapted to receive signals corresponding to an uplink, each input port having a predetermined bandwidth;

    a plurality of output ports adapted to output signals corresponding to a downlink, each output port having a predetermined bandwidth;

    an A/D converter associated with each input port and arranged to convert an uplink signal of a predetermined bandwidth to digital sample form;

    a D/A converter associated with each of the output ports and arranged to convert a processed digital signal of a predetermined bandwidth to an analogue downlink signal;

    a plurality of frequency demultiplexers, each connected to one or more of the plurality of A/D converters and arranged to separate a sampled bandwidth of one or more of the sampled uplink signals into a plurality of channels;

    a channel level processing stage associated with each of the channels and arranged to route processed channels to any of the plurality of output ports; and

    a plurality of frequency multiplexers, each connected to the channel level processing stage and to one or more of the plurality of D/A converters and arranged to combine a plurality of routed channels.
