摘要

微小卫星一般使用两个小视场星敏感器以实现高精度姿态测量,但小视场容易导致观测星数量不足。组合星图技术可以缓解该问题,但其受星敏感器安装角度影响很大。分析了双星敏感器安装角度对组合星图识别效率的影响,并开展了仿真研究。实验结果表明:角距匹配得到的导航星对个数,随参考星对角距近似呈正弦函数变化,在约 90°时达到极值;随容差增大而增大,且容差对导航星对个数极差影响很大。在组合星图技术中,双星敏感器应避免使用 90°安装角,且安装角越小,组合星图识别效率越高。

Abstract

Generally, two star trackers with small FOV (field-of-view) are used to maintain a high accuracy for micro-satellite’s attitude determination. Due to the small FOV, a sufficient number of stars for identification cannot be always captured. Combined images technique can be used to ease this problem, but its efficiency is highly affected by the mounting angle between two star trackers. The role made by the mounting angle is analyzed and simulated here. Results show that the number of guide starpairs matched to the reference angular distance changes like the sine function as the reference angular distance changes, and it reaches its extremum when the angular distance is about 90 degrees. And it increases as the tolerance increase. The extremum difference of the numbers of guide starpairs is highly affected by the tolerance. Therefore, the mounting angle should not be 90 degrees in combined images technique. The efficiency of the identification is higher as the mounting angle is smaller.
