Study on technique of high time coherence used in real-time distributed interactive simulation
分布式实时仿真系统高精度时间同步技术研究

In LAN which use PC and Windows operating system, accurate and effective time coherence using the pattern that software cooperate with hardware is one of the keys for real-time distributed interactive simulation system to improve fidelity and decrease cost. A brief time synchronization algorithms in LAN (LTS algorithms) was bring forward,and a new clock was designed based on resource of PC. In LAN, LTS algorithms has better time adjust effect. The new clock is better than the system clock of Windows operating system in performance. At last, a integrated scheme of time coherence was designed,and the purpose to get accurate and effective time coherence and to decrease cost was realized.
