摘要 介绍了卫星钟差数据仿真方法以及基于星间双向测距的导航卫星两步滤波时间同步算法。仿真数据结果表明,与一步滤波方法相比,两步解算方法的时间同步精度有一定提高。 To maintain the positioning and navigation function of our navigation system, the crosslink ranging measurement is used to calculate the ephemeris and clock error. The simulating method of clock error is presented. A two-step time synchronizing algorithm is introduced. The validation of the algorithm was verified by the simulating data. The results show that the two-step algorithm is slightly better than one-step algorithm.
