Thenew navigationtime synchronization method is a breakthrough in existing navigation systems time synchronization accuracy limit,and it is an effective way to reduce system construction costs.By placing more accurate atomic clock in GEO satellites,it can synchronize with ground systems and generate time reference,the GEO satellites can give time to other navigation satellites,the new system can achieve high-precision time synchronization.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.
