Implementation and operational considerations for CODE

The Cooperative Olympus Data Experiment (CODE) is designed to allow experiments with a very small aperture terminal network using the Olympus satellite 20/30 GHz transponder. Two aspects of the system, implementation and possible modes of operation, are covered. Link budget calculations for both inbound and outbound channels are presented which include a 3 dB implementation margin for effects such as filter intersymbol degradation. Extensive system simulations, of which some results are included, have been performed using TOPSIM 3 to assess the adequacy of this implementation margin. Various modes of operation for CODE, are discussed. The software requirements and the type of low level communication protocols required are outlined.
