摘要: 提出了一种自适应的时钟同步算法,该算法考虑了网络延迟带来的影响,考虑了历史平均更新周期与当前状况,能根据自身时钟偏移程度动态地调整下一次同步周期,保证了时间精度,提高了更新的可靠性。目前已经应用于实时分布卫星测控的原型系统,在实验中证明算法的可行性。

Abstract: This paper presents a self-adaptive clock synchronization algorithm, which considering the effect of network delay and historically average updated period, can dynamically adjust the next period according to the maximum drift rate. This algorithm can guarantee the time precision and enhance the reliability of updates. Now the algorithm has been applied in the real-time distributed satellite monitoring and controlling prototype system. It has been proved to be effective in experiences.
