| Abstract: | In recent years,time-keeping ability of the local coordination time UTC(BIRM) improving steadily.Up to now,the relative frequency deviation between UTC(BIRM) and UTC is better than 1E-15,the time deviation is better than 16ns.In this paper,the composition of time-keeping system,local frequency steering and master-backup time synchronization technology,and the research of TA(BIRM) algorithm are introduced briefly. |
