| 摘 要： | 联合战术信息分发系统JTIDS(Joint Tactical Information Distribution System)系统采用无中心节点的时分多址(TDMA)的网络接入协议,针对TDMA网络时隙同步的要求,各终端必须有统一的时间基准的特点。基于HLA/RTI仿真平台,对网络延迟进行了测试,针对RTI中联邦成员的时间延迟很不稳定的问题提出并实现了一种简单高精度的软件时钟同步方法。该方法既可以降低网络延迟不确定性的影响,又考虑了时钟漂移的影响,具有很好的精度。

| Abstract: | JTIDS of American Army adopts TDMA communication protocol that has no central node. TDMA network is a kind of synchronization network and must have unities time benchmark and the time slot of node must synchronize with time benchmark. Based on HLA/RTI, the time delay of network transmission is tested. Finally for the Federate Ambassadors of RTI has the unstable time delay, one simple software time synchronization methods with high precision is proposed and realized. That method not only can lower the network to delay the indetermination influence, but also considered the influence of the clock drift, have excellent accuracy. |
