ABSTRACT:
A satellite constellation has a plurality of network satellites that form a network. A gateway satellite is disposed adjacent to the network. The gateway satellites receive an optical signal from the network and converts the signal to an electrical signal. The gateway satellite has a sorter and a reshaping circuit for reshaping the electrical signal to form a reshaped signal. The electrical signal is converted back to an optical signal corresponding to the reshaped signal. The optical signal corresponding to the reshaped signal has reduced noise in comparison to the input optical signal. The optical signal is then retransmitted to another satellite.
