Research on Satellite Orbit Prediction by Runge-Kutta Based on J2 Perturbation Term and Hermit

在给出卫星轨道参数的描述方法的基础上,分析了其坐标变换方法,并通过Matlab进行了编程实现和经过其它坐标变换软件的验证;简析了卫星轨道的预报方法,着重分析了数值法(基于J2项的Runge_Kutta方法、Hermite方法)等的预报,并以STK中HPOP预报结果为真值,对其预测性能进行了仿真分析。

A deduction of coordinate transformation of satellite orbit based on its describe method,and the method are pro-grammed by Matlab and validated by other coordinate transformation software.Then numerical method(such as Runge_Kutta meth-od based on J2 perturbation term,Hermite method)of satellite orbit prediction are analyzed,their prediction performance are simu-lated and compared with the HPOP prediction result in STK.
