利用星敏感器的卫星姿态确定的信息滤波

针对利用星敏感器矢量测量的卫星姿态滤波的问题给出了一种矢量测量的信息滤波器。分析结果表明该滤波器可以统一的形式处理单矢量测量和多矢量测量的结果，简化了计算机程序，并且相对于经典的卡尔曼滤波器简化了计算量。仿真研究的结果验证了该滤波器应用于卫星姿态确定的可行性。

AN INFORMATION FILTER FOR THE SATELLITE ATTITUDE DETERMINATION WITH STAR SENSORS

In this paper an information Filter with Vector Measurements (IFVEM)is presented to cope with the problem in satellite attitude filtering with the vector measurements of star sensors.The analyses show that the IFVEM can process both the single vector measurement and multiple vector measrement in a common frame and simplify the computer program, and it saves computation compared to the conventional Kalman filter.Simulation results are presented to demonstrate the feasibility of the IFVEM in satellite attitude determination.
