摘要
介绍了一种全天球太阳矢量确定算法,算法采用的敏感器组件可以减少敏感器安装的约束条件,并在此基础上设计了一种基于太阳矢量的角速度阻尼算法,能够有效解决地磁矢量测量精度对于阻尼算法的影响。仿真结果表明算法能够确定任意姿态下的太阳矢量和地磁矢量低测量精度下的角速度阻尼,具有重要的工程实践意义。
A whole celeste sun vector determination algorithm is introduced in this paper,which can reduce the constraint conditions by utilizing the special sensor module in the algorithm,and a sun vector-based angular rate damping algorithm is designed on the basis of the sun vector determination algorithm. The simulation result demonstrates that sun vector can be determined by no matter the satellite attitude and angular rate damped with a low measurement precision of the magnetic vector. The algorithm can be served as significant application value in engineering.
