Paper Abstract

Current medium to low data rate low earth orbit to geostationary orbit intersatellite link services are implemented or designed at S band. These services include those provided by TI)RS and planned for Euro-DRS. S band links have a number of undesirable charateristics which make them less than optimum for this function. These include the need for large antennas at both 14E() and CEO, and operation in a high RF1 environment. This paper discusses the results of a study performed by British Aerospace in co-operation with the European Space Agency into the use of optical communications for this service. Projected advances in semiconductor laser diode powers of up to 1W CVV in a diffraction limited beam are considered. The system derived is designed to serve up to eight users simultaneously from GEO with data rates of up to 2Mbps. The payload demonstrates significant mass, accomodation, and operational advantages over existing S band systems, and suggests that optical technology will have applications outside conventional high data rate ISI, payload designs.
