Abstract An experimental rule-based system for optimizing user spacecraft communications configurations has been developed at NASA to support mission planning for spacecraft that obtain telecommunications services through NASAs Tracking and Data Relay Satellite System. Designated ECCO (Expert for Communications Configuration Optimization), and implemented in the OPS5 production system language, the system has shown the validity of a rule-based systems approach to this optimization problem. This article discusses the development of ECCO and the incremental optimization method on which it is based. A test case using hypothetical mission data is included to demonstrate the optimization concept.

A method to mitigate interference while minimizing unnecessary scheduling restrictions on the NASA tracking and data relay satellite system (TDRSS) network and user resources, based on consideration of all relevant communications parameters, has been developed. This method also can be used as the basis for analysis, evaluation, and optimization of user schedules with respect to communications performance. The method and its proposed application to scheduling in space communications are described. Test cases relative to planned missions, including the Earth Observing System, the Space Station manned base, and the Space Shuttle are discussed.<<ETX>>
