A satellite subsystem for a satellite employs a reconfigurable communications payload and active array antennas. The subsystem includes an active receive array antenna having a reconfigurable beam forming network for forming input beam signals from input signals received by the receive antenna from sources. An input switch matrix power divides the input beam signals into sets of input beam signals. Each of the channel signals corresponds to a respective channel of the input beam signals. The subsystem further includes a channelizer having a plurality of channel processors each receiving at least one input beam signal from the input switch matrix. The channel processors filter the input beam signals into channel signals. Each of the channel signals corresponds to a respective channel of the input beam signals. The channel processors change the frequency of at least one channel signal to route the at least one channel signal to a different channel than the respective channel of the input beam signals. An output switch matrix combines the channel signals into output beam signals. Each of the channel signals corresponds to a respective channel of the output beam signals. An active transmit array antenna having a reconfigurable beam forming network forms output signals from the output beam signals for transmission by the transmit array antenna to destinations.
