摘要
Abstract
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 ps to meet the tactical information system clock synchronization accuracy requirements.关键词
