| 摘 要： | 针对基于星敏感器的三轴稳定卫星姿态确定系统,总结比较了目前用于姿态确定的常用姿态敏感器的性能,引出了星敏感器的核心-星图识别算法,进而分析比较了当前星敏感器星图识别相关的几种算法的优缺点,重点研究了栅格算法;并在此基础上,提出用矩阵星图识别算法,建立了基于矩阵星图识别算法进行卫星三轴姿态确定的数学模型,从而简便、快捷地求出卫星任意时刻的三轴姿态参数;最后利用Matlab分别实现了用栅格算法和矩阵法进行星图识别的仿真,验证了矩阵识别算法的优点,对于研究卫星姿态确定和提高星图识别算法的效率和精度有一定的参考价值.

| Abstract: | This paper deals with attitude determination of three-axis stabilized satellites using star sensor, analyzes and compares some star pattern recognition algorithms, and advances a matrix algorithm. Then, bring forward the method for attitude determination based on the matrix algorithm, and simulate the process of star pattern recognition with the the matrix algorithm and the grid algorithm separately using Matlab. Simulation results show that the matrix algorithm spends less time than the grid algorithm. |
