| 精确协同作战作为信息化条件下作战形态的必然发展趋势，其对作战平台间高精度时间同步提出了较高的要求。针对该要求，在分析了战术数据链往返计时（RTT）时间同步算法的基础上，提出了卫星导航载波相位差分GPS（DGPS）技术与数据链高精度时间同步算法，利用卡尔曼滤波构建时间同步计算算法模型，实现高精度的时间同步。仿真结果表明该算法可提高时间同步精度到3 ns。 |

| Abstract: |
| The precise cooperative combat is an inevitable development trend under the condition of informationization,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) technology,a time synchronization model is constructed by Kalman-filtering to obtain high-precision time synchronization.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. |
