摘要: 推导了利用四阶龙格-库塔方法对GLONASS卫星运动方程进行轨道积分的计算公式,根据实际数据处理结果对积分区间、积分步长作了一定分析,在对定步长积分方法和变步长积分方法分别进行介绍的基础上,对两者的结果作了比较。Abstract: Formulas are detailed deduced using Rung-Kutta method for orbit integral of GLONASS satellite motion function,and the integral scope and integral step on the basis of processed result using actual data are analyzed.A comparison is made between fix-step integral and vary-step integral after description of the two methods.
