  • Satellite anomaly detection method and system for adversarial network auto-encoder
    Patent number: 12093804
    Abstract: The present disclosure provides a satellite anomaly detection method and system for an adversarial network auto-encoder. The method includes: obtaining a variational auto-encoder and a generative adversarial network; adding the generative adversarial network to the variational auto-encoder, and determining an optimized variational auto-encoder; obtaining to-be-detected satellite telemetry data; and determining a current operating status of a satellite based on the to-be-detected satellite telemetry data by using the optimized variational auto-encoder, where the current operating status includes a normal operating state or an abnormal operating state. The satellite anomaly detection method and system for an adversarial network according to the present disclosure solve the low accuracy problem of automatic satellite anomaly detection in the prior art.
