说明：  以组合大视场星敏感器的卫星自主导航方法为例,设计改进的广义卡尔曼滤波算法,通过仿真,可以看出该算法对减小采样周期所带来的轨
(Taking the satellite autonomous navigation method of the combined large field of view star sensor as an example, an improved generalized Kalman filter algorithm is designed. Through simulation, we can see the orbit caused by the algorithm to reduce the sampling period.)
