I. Introduction
Since the launch of the first spacecraft by humans in the 1950s, humanity entered the space age. After decades of development, spacecraft have become increasingly sophisticated in their functionality, and spacecraft systems have grown in complexity, with a diversification of platforms. The consequent challenge is how to ensure the safe operation of spacecraft. Timely sensing of a spacecraft's status and the detection of anomalies are crucial methods for ensuring spacecraft safety. Additionally, due to limitations in measurement methods and potential interference in telemetry transmission, the data we collect may contain noise. Therefore, our anomaly detection methods should exhibit robustness.
