| 摘 要： | 提出了一种在自旋稳定卫星自旋轴与几何体轴重合或几乎重合时只利用太阳角计算自旋卫星姿态的方法。给出了方法的原理及适用范围。研究表明：定姿精度仅与太敏测量精度有关,减小了传统方法中太敏与地敏两项测量误差产生的误差,方法原理简单、精度高。由实际卫星数据的长期验证可知：方法能在卫星自旋轴与实际几何轴偏差较小时实现快速定姿,定姿结果满足要求。

| Abstract: | A new method for attitude calculation of spin-stabilized satellites,which only needed the solar angle,was put forward when the spin-stabilized axis was superposition with the geometry axis of the satellite in this paper.The principle and the applicable range were explained in the study.The study showed that the accuracy of the attitude determination was related to the measurement of the solar sensor only,which reduced the error caused by the measurement errors of the solar senor and the earth sensor in trad... |
