摘　　要：为实现低轨卫星轨道的快速确定和预报,基于单站单圈雷达站测量数据采用遗传算法和最小二乘法对卫星初轨确定及轨道预测问题进行了研究。通过比较分析不同观测误差下两种方法的仿真结果,验证了初轨确定过程中两种方法的可行性,同时指出了各自的优缺点和适用条件,为不同观测条件下卫星最优初轨确定的方法提供了参考。To achieve fast determination and prediction of the low earth orbiter,this paper is based on the measurement data of single lap radar station using genetic algorithm and least square method studies the determination and the prediction of satellite orbit. Through the comparison of two simulation results under different observation error,the paper confirms the feasibility of the two methods in the initial orbit determination process,and points out their advantages and disadvantages and suitable conditions,to provide a reference for the determination of the satellite initial orbit in different observation conditions.
