中文摘要: 下一代地磁导航等空间任务对地球磁场测量卫星提出了迫切的需求, 高精度地磁场测量卫星需要极高的姿态测量精度和空间剩磁环境, 对星敏感器提出了新的要求。针对这一需求, 研究了低剩磁高精度星敏感器的改进设计方法。采用三视场分体结构设计,提高了数据更新率,通过数据融合提高了姿态确定精度,同时对光学头部进行了精细化降剩磁设计。仿真和测试结果表明,改进的星敏感器设计方法能够实现较低的剩磁和较高的定姿精度, 满足地磁场测量卫星的应用需求, 具有较高的应用价值。

Abstract:The next generation space mission of geomagnetic navigation puts forward urgent demands on the geomagnetic measurement satellite, and the high precision satellite requires extremely high attitude measurement accuracy and space environment with residual magnetic, which puts forward new requirements on the star sensor. Aiming at the requirements, the improved design method with low remanence and high precision star sensor is studied in this paper, which adopts the three fields-of-view design and the separated body of structure to improve attitude measurement precision. Meanwhile, it improves the attitude determination accuracy by increasing the data updating rate and data fusion, and designs the optical head of the star sensor to reduce remanence. Finally, the simulation and test results show that the improved design method of star sensor can achieve the performances of low remanence and high attitude determination accuracy, which satisfies the demand of geomagnetic measurement satellites and has high application value.
