Study on Aerospace Layering Time Synchronization Architecture and Time Synchronization Algorithm
The rapid development of various kinds of aerospace application systems requires the appropriate high-accuracy time and frequency standard.This problem can be effectively solved by establishing suitable time and frequency standard in aerospace.Based on the establishment of aerospace satellite visual model,the simulation of satellite visual time on 3-layer constellation structure,including GEO satellite,IGSO satellites and MEO satellites,has been conducted.The visual features of this constellation have been gained.Combining with the major influencing factors of satellite clock correction error,aerospace time synchronization architecture on the basis of layering has been proposed.The time synchronization algorithm in line with this architecture has been researched.The results show that aerospace time frequency standard established based on this layering time synchronization architecture can meet the demand on high-accuracy time frequency of future aerospace application systems.
