基于卫星无源探测的空间飞行器的轨道估计

Space Vehicle Orbit Estimation Based on Passive Detection Satellite

通常无源探测卫星采用的红外探测技术属于被动探测技术,单颗星可以探测到目标的方向而无法确定目标的距离。该文结合立体几何的知识,利用双星逐点交汇定位的方法,并在仿真观测数据的基础上,采用常微分方程组的数值解法和利用伪逆矩阵求解矩阵方程等方法,实现对空间飞行器的轨道估计。

Usually infrared detection technology used by passive detection satellite belongs to passive detection technology,so single satellite can detect the direction of the target but cannot detect the distance of the target.Combined with the knowledge of solid geometry,this paper puts forward a method using pointwise intersection of two satellites to solve the positioning problem,and based on the simulation observation data,by using the numerical solution of ordinary differential equations and pseudo inverse matrix solving matrix equation and other methods,the paper realized spacecraft orbit estimation.
