摘　　要：随着速度大于4马赫的超高速导弹技术的逐步成熟,针对超高速导弹突防的相应防空导弹、卫星通信、雷达组网等领域都对时间同步精度提出更高要求。将用于工业控制以及测量领域的高精度时间协议—IEEE1588v2协议引入战术信息系统中。在简单介绍IEEE1588v2协议的基础上,设计基于该协议的软件实现方案;通过同步性能测试和PTP报文分析,验证该方法的可行性,为战术信息系统中的时钟同步技术研究提供参考;分析影响精度的因素和提高精度的方法。实验结果表明,主从时钟同步的精度稳定在30μs左右,满足战术信息系统对时钟同步精度的要求。With the development of ultra high-speed missile technology with speed more than 4 Mach, the fields such as corresponding anti-aircraft missile, satellite communication and radar networking for ultra-high-speed missile penetration have put forward higher requirements on the time synchronization precision. In view of this situation, high precision time protocol for industrial control and measurement--IEEE1588v2 protocol has been applied to the tactical information system. Based on the brief introduction of IEEE1588v2 protocol, the software realization scheme was designed. The synchronization performance test and the PTP message analysis verified the feasibility of this method, and provided reference for the research of clock synchronization technology in tactical information system. Moreover, the factors influencing accuracy and the method of improving precision were analyzed. The experimental results show that the accuracy of master-slave clock synchronization is stable within the 30 Ixs to meet the tactical information system clock synchronization accuracy requirements.
