摘　　要：分析了空间目标两行轨道根数（TLE）的格式及构成；阐述了相应的SGP4／SDP4轨道近似解析模型算法；提供了轨道坐标系与J2000．0坐标系及观测地平坐标系之间的转换关系。研究了ASCOM控件的用法，并结合TLE数据计算结果编程实现了用Meade望远镜对空间目标的自动搜索与跟踪观测。The format and composition of two-line element sets were analyzed firstly. And then Simplified General Perturbations Version 4 and Simplified Deep-space Perturbation （SGP4/SDP4） orbital model which developed from analytic orbital theory were introduced. And the coordinate transformation from True Equator and Mean Equinox of Date to J2000.0 and to topocentric-horizon system was provided. Space object observation software based on TLE and ASCOM control with Meade telescope was developed.
