| 摘 要： | 针对导航GPS/GLONASS导航数据处理的需要,分析了GLONASS广播星历、地固坐标系PZ-90下卫星加速度简略公式,推导了利用定步长四阶龙贝格-库塔对轨道进行积分的计算公式,提出一种新的不需要进行轨道拟合的编程实现方法,该方法具有结构简单、运算快的特点,最后根据实际计算结果对积分区间、积分步长与积分坐标精度之间的关系进行分析,给出了实际积分计算合适的步长.

| Abstract: | In order to meet the need of dealing with GPS/GLONASS navigation data,this paper analyzes the broadcast ephemeris of GLONASS and formula of the satellite acceleration in PZ-90 coordinate.It derives the calculating formula of orbit integral by using the fixed step and four-rank Runge-Kutta method,puts up with a new programme which don't need fitting.The structure of this method is simple and the speed is quick.Finally,it analyzes the relationship between integral step and integral interval with the precision... |
