A microcomputer based expert system is being developed to assist in the diagnosis of satellite anomalies caused by the space environment. The expert system is designed to address anomalies caused by surface charging, bulk charging, single event effects, and total radiation dose. These effects depend on the orbit of the satellite, the local environment (which is highly variable), the satellite exposure time, and the hardness of the circuits and components of the satellite. The expert system is a rule-based system that uses the Texas Instrument Personal Consultant Plus expert system shell. The completed expert system knowledge base will include 150 to 200 rules, as well as a spacecraft attributes database, a historical spacecraft anomalies database, and a space environment database which is updated in near real time. Currently, the expert system is undergoing development and testing. The status of the expert system development completed in FY88 is reviewed.
