Abstract: In compliance with NASA administrator Daniel Goldin's call for faster, cheaper, better NASA projects, the Center for EUV Astrophysics (CEA) in cooperation with NASA Ames Research Center has developed and deployed a partially autonomous satellite-telemetry monitoring system to monitor the health of the Extreme Ultraviolet Explorer (EUVE) payload. Originally, telemetry was monitored on a 24 hour basis by human operators. Using RTworks, a software package from Talarian Corporation, our development team has developed a rule-based, expert system capable of detecting critical EUVE payload anomalies and notifying an anomaly coordinator. This paper discusses the process of capturing and codifying the knowledge of EUVE operations into rules and how our rule-based system is applied in EUVE autonomous operations.
