Abstract
The precise cooperative combat is an inevitable development trend under the condition of infor-mationization,so high-precision time synchronization is urgently needed between different platforms. By analyzing the round trip time( RTT) clock synchronization algorithm and the differential GPS( DGPS) tech-nology,a time synchronization model is constructed by Kalman-filtering to obtain high-precision time syn-chronization. Algorithm process is provided and algorithm strategy is simulated. The simulation results show that the precision of time synchronization can be improved to 3 ns.关键词
