A Novel Spacecraft Attitude Recovery Method Based on Platform Vibration

Attitude data plays a key role for spacecraft. However, the acquired attitude data may include errors or data loss caused by the attitude determination system (ADS) or outside noise distortion. The spacecraft attitude control mission and primary product geometry accuracy will be influenced by continuous attitude loss. Furthermore, limited by the sampling frequency of the attitude sensor, the values between adjacent sampling points are missing, which would not meet the requirements of high-accuracy attitude maneuvering. To recover the attitude data, we proposed a novel attitude data recovery strategy, which could be suitable for some spacecraft with certain loads. Spacecraft platform vibrations can be detected and used for attitude recovery. In this study, the ZY302 satellite was used as an example to verify the effectiveness. The experimental result showed that the strategy could meet the requirements of attitude recovery, and the correlation between the recovered attitude and data was better than 0.9.
