基于PTP授时的同步精度测试方法研究

随着现代武器打击精度的提高，指控系统对时间同步的要求也随之提高，这就对系统授时方案中的网络架构、主时钟以及授时板卡的时间同步精度提出了新的要求。本文主要针对PTP授时方案中的对时精度给出测试方案。测试结果表明，PTP授时模式可满足系统对时间同步精度的需求。

Research on synchronization precision test method based on PTP timing

With theimprovement of the accuracy of modern weapons to attack,command and control system of the time synchronization requirements are also increased,which timing system scheme of network architecture,the master clock and timing board time synchronization accuracy of proposed new requirements. In this paper, PTP time synchronization in the time synchronization accuracy test scheme is given.The test results show that the PTP timing mode can meet the system requirements for time synchronization accuracy.
