| 摘 要： | 卫星在运行过程中,星敏感器视场若受到太阳光、月球反射光等杂散光影响,将会大大降低星敏感器指向精度。通过调用卫星工具包STK(SatelliteToolKit)高精度轨道预报模块与高级分析模块,利用STK\Matlab无缝接口与Matlab进行数据交互,建立了星敏感器视场分析模型,并完成了杂散光进入星敏感器视场可视化仿真。研究方法和仿真结果对于星敏感器的工程设计、提高星敏感器精度及准确性具有一定的借鉴意义。

| Abstract: | With a satellite running, if the diffuse light such as the sunlight or the moonlight entered the view field of star sensor, the precision of star sensor would be debased. Using the Satellite Tool Kit (STK) software, the system exchanged data with Matlab by STK\Matlab interface, built the model for analyzing the view field of star sensor and finished the visual simulation of the view field encountering the diffuse light. The research is useful to the related engineers in designing the star sensor and enhancing the precision accuracy of star sensor. |
