对多个偏置动量卫星在轨飞行的遥测数据观察后发现,其中一些卫星的X轴和Z轴控制误差较大,且有明显的常值偏差存在.对这一现象进行分析,从偏置动量卫星的控制原理上找到了姿态偏差较大的原因,进而提出修正方法.在轨飞行测试表明:原姿态超差的偏置动量卫星采用本方法后,姿态控制精度得到明显改善,证明了本方法行之有效.
After observing telemetry data of a plurality of orbiting momentum satellites in orbit, it was found that some of the satellites have large control errors in the X axis and the Z axis, and obvious discrepancies exist in common. This phenomenon is analyzed from the offset Momentum satellite control principle to find the reason of the larger deviation of the attitude, and then put forward the correction method.Orbit testing shows that: the original postures bias bias momentum momentum satellite using this method, the attitude control accuracy has been significantly improved, proved this The method works well.
