摘　　要：运用卫星探测空间飞行器对国防科技的发展有其深远意义,而无源定位则是实现目标探测的一项关键技术。针对空间飞行器的运行轨道来说,其主动段起关键作用,因此,卫星对空间飞行器主动段轨道的无源探测估计与误差分析至关重要。在对大量数据分析的基础上,利用自适应定点的四阶龙格库塔算法求解卫星二阶微分运动方程,确定了其轨道,建立了数值解模型、坐标转换模型、空间飞行器轨道估计模型等多种数学模型,运用Matlab、Mathematica等软件对数据进行了分析和处理,利用图表直观地显示了其结果。The use of satellite space vehicle has？hada profound？impact？on the national defensescience and technology,while the passive location is a key technology to realize the target detection. Inview of the operational orbit of the space vehicle,the active part of the space vehicle plays a key role.Therefore,the satellite is very important for the passive detection and error analysis of the activesegment of the space vehicle. In order to estimate the orbit,a fourth-order Runge-Kutta method basedon the adaptive point is proposed to solve the satellite＇s second order differential equations of motion.Through analysis of large amounts of data,this thesis aims to establish the numerical solution of themodel and the coordinate transform model,space craft orbit estimation model and a variety ofmathematical model. With the help of MATLAB,Mathematica software, the data is thoroughlyanalyzed and processed,and the result is very obvious by using a？set of？diagrams.
