摘要

摘要:为了方便星图识别算法和星敏感器性能的测试,设计了一种CCD星图模拟器,开发了星图模拟软件。采用高分辨率显示设备及平行光管模拟无穷远处平行光,实现了高质量星图的模拟。通过高精度QUEST算法求解姿态,对模拟的星图进行了验证。计算了3颗以上恒星的偏航角、俯仰角和滚动角,对100幅模拟星图进行了统计分析,结果显示其定位精度已达98.1%。目前,该星图模拟器已成功用于实际项目,为后续的测试星图识别算法提供了良好的依据,并缩短了开发周期。

Abstract:In order to test the identification algorithms for a star map and evaluate the performance of a star sensor, a CCD star map simulator was proposed and the star map simulation software was developed in this paper. The system used a high-resolution display device and a parallel light tube to simulate the parallel light of an infinite distance to obtain the high quality star map. The validation on star map by an attitude determination algorithm was also presented. By calculating the attitude angles for three stars more accurately, more than 100 star maps were analyzed. The results indicate that the positioning accuracy has reached 98.1%. The designed simulator has been used in a practical operation, the experimental results show that it can offer good information for verifying star map identification algorithm and evaluating star sensor performance, and it also can shorten the development cycle.
