摘要：

The time-synchronization has no ground time criterion in the model of autonomous time-synchronization, time precision keep on the navigation satellite itself. When can make GEO satellite as time norm, and use satellite-satellite chain to give other satellite. This paper design the navigation constellation of the new satellite-navigation-system, and configure the satellite clocks, simulate all kinds of constellation time-synchronization precision, educe the satellite clock configure scheme in the new navigation system. Due to the introduction of high-precision optical clocks, the overall time of the entire navigation constellations drift is smaller, the accuracy is much higher than the link between self-ordinary; and because the presence of high-precision clock, the time synchronization algorithm's requirements are lower, general EKF can meet the requirements.
