现代战机强调航电系统的高度综合化以及编队协同作战，而高精度的时间同步是其实现的基础。针对该需求，提出了一种兼顾飞机平台内部时间同步和编队时间同步的方法。通过建立飞机平台内部时间中心，结合飞机航电系统本身具备的卫星导航授时能力以及数据链授时能力，可以实现飞机平台时间和编队时间的高度统一。误差分析结果表明，其实现的平台内部及编队平台间时间同步精度可达到100 ns量级。该方法实现原理简单，能直接应用于工程化设计。

Modern fighters stress high integration of avionics and cooperative engagement, and time syn-chronization 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 syn-chronization 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.
