The Aerospace Corporation has developed a real-time version of its Space Environmental Anomalies Expert System. Given that a geosynchronous vehicle has experienced an anomaly, SEAESRT analyzes 5 different space environment effects that might have caused the anomaly. We use cumulative probability distributions obtained from historical observations to develop situational awareness levels for real-time data. We presently use the 97th percentile to indicate the severe level for each parameter, based on the 97th percentile of Kp, which is Kp>7. SEAESRT provides confidences between +1.0 (Definitely For) to -1.0 (Definitely Against) for each environmental effect being the possible cause of the anomaly. We have also developed a front end and graphical user interface to automatically manage the available environment measurements and prepare the inputs to SEAESRT. This new system includes heads-up status displays as well as the ability to ingest new data in real-time either using the GUI or using batch programs.
