The proposed approach uses Physics-Informed Real NVP neural networks to develop robust fault detection methods for space missions, which are crucial for ensuring mission success and safeguarding valuable assets. The novel method combines self-supervised learning with sensor data permutation to improve fault detection in satellite multivariate time series. Experimental results demonstrate significant performance improvements across various configurations, including pre-training with self-supervision, multi-task learning, and standalone self-supervised training. Notably, the self-supervised loss alone achieves the best overall results, indicating its effectiveness in extracting relevant features for fault detection.

A new way to detect faults in space missions uses special kinds of neural networks. These networks are great at understanding complex data and can help make sure space missions don’t fail due to equipment problems. The method works by looking at how sensors collect data and then using that information to identify when something is wrong. Tests show that this approach really helps improve fault detection, especially when it’s used alone.
