A High Precision Time Synchronization Scheme for Avionics System
Duan Qiu-hu · Telecommunication Engineering · 2014
Modern fighters stress high integration of avionics and cooperative engagement,and time synchronization with high precision is the basis of these implementation.According to this demand,a new method considering both aircraft internal time synchronization and formation exterior time synchronization is propposed.Through establishment of aircraft internal time center,considering global navigation satellite system(GNSS) time service ability and data link time service ability of flither avionics itself,the method can achieve time unification of both aircraft internal and exterior time.Error analysis shows that the synchronization precision of both internal and formation time can reach 100 nanoseconds.The implementation of the method is simple and it can be directly applied in engineering design.
