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.
