Timekeeping of NTSC in Recent Years

Abstract

Since 2004, the National Time Service Center of Chinese Academy of Sciences (NTSC) has been greatly improving in the number of atomic clocks, time comparison system, remote time transfer system, and so on. With the improvement of frequency control technology for the master atomic clock, the accuracy and stability of the Coordinated Universal Time UTC (NTSC) have also noticeably increased. From 2008 to 2009, the deviation between UTC (NTSC) and UTC has been less than 20 ns. The middle-term and long-term stability of the local atomic time TA (NTSC) has also been greatly improved.
