在介绍接收GPS(导航星全球定位系统)时频信息,进行远距离时间同步的基本原理和方法之后,着重分析了国内首次 GPS 共视法时间同步实验的结果和搬运钟验证的结果。实验取得了上千公里两地钟 GPS 共视同步误差优于 13ns、单站单星连续测量15分钟不确定度小于15ns、搬运钟验证符合程度优于80ns 的好成绩。
After introducing the basic principles and methods of receiving time-frequency information of GPS (Navigation Satellite Global Positioning System) and carrying out long-distance time synchronization, the results of the first GPS common-view time synchronization experiment and the verification of handling clock are mainly analyzed. Experiments have achieved thousands of kilometers of GPS clock sync synchronization error is better than 13ns, single-station single-star continuous measurement of 15 minutes less than 15ns uncertainty, handling clock verification compliance better than 80ns good results.
