Research on Spacecraft Anomaly Detection Method Based on Data Drive

Monitoring and evaluating of satellite status, timely and effectively finding and handing of anomalies, and ensuring its safe and reliable operation are the key points of on-orbit management of satellites. In view of the limitations of traditional spacecraft anomaly detection methods, an anomaly detection method based on data drive is proposed, and then the method is verified, by extracting and processing real telemetry data from orbiting satellites, the image generation and feature recognition are completed, which proves that this method can not only find the satellite anomaly in time, but also can make up for the detection that the alarm threshold cannot recognize the trend of the telemetry curve, effectively guarantees the safe operation of the satellite in orbit, and provides a reference for the on-orbit management of satellites.
