| 摘 要： | 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．

| Abstract: | Observation on several momentum biased satellites' data in-orbit,some satellites have bad control accuracy on X and Z-axis direction,and the error is constant.Based on the analysis of the questions,the paper presents the reasons of the bad accuracy,and finds an approach to improve the accuracy.When the approach is used in the attitude determining process,the attitude control accuracy is improved remarkably. |
