摘要
介绍了基于多源授时的广域网时间同步系统，系统建立多个授时服务节点，每个授时服务节点通过对多种授时源的融合和原子钟保证授时精度和系统可靠性，使用网络时间同步技术保证广域网的用户的授时精度。测试结果表明，该系统具有可靠性高、授时精度高等特点。
The paper introduces a WAN time synchronization system based on Multi-source time Service. The timing sources from the several timing nodes in combination with atomic clock can make sure the timing accuracy and system reliability. The network time synchronization can ensure the timing accuracy of WAN users. The result indicates that the system is of high reliability and high timing accuracy.
