The National Geophysical Data Center (NGDC) has implemented the Space Environmental Anomalies Expert System Real Time (SEAESRT) system within NOAA. Originally developed by The Aerospace Corporation, the algorithms with comprise the SEAESRT system provide near-real-time estimates of the likelihood of spacecraft anomalies for satellites in geostationary orbit. Spacecraft
anomalies are strongly correlated with the local radiation environment and the general level of geomagnetic activity. SEAESRT uses space weather data available from NOAA's Geostationary Operational Environmental Satellite (GOES) at a particular local time along with other ancillary real-time data and calculates a set of hazard quotients associated with the geostationary environment at all local times. NGDC is validating the SEAESRT results before making SEAESRT available for implementation in operations. We present here initial results and a demonstration of the utility of SEAESRT.
