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’srequirements are lower,general EKF can meet the requirements.
