摘要
给出采用法方程叠加的单天解轨道合成多天解轨道的方法,结合GPS实测数据,验证了多天解轨道合成可有效提高单天解轨道的精度,并使定轨结果更加平滑;单天轨道边界处伪随机参数的引入可有效改善轨道跳变现象。
Synthesis method of n-days orbit with one-day orbit based on pseudo-stochastic parameters is present. The method is validated using GPS real data. The calculated results show that the method is correct and effective. The precision and smoothness of one-day orbit solution is improved effectively. Especially,the phenomenon of orbit jump is improved obviously by added pseudo-stochastic parameters at the edge of one day.
