NTSC Researchers Establish a Fusion Time Scale APT
NTSC Researchers applied the comparison data between pulsar timing observations and atomic clock sets to establish a fusion time scale APT (Atomic-Pulsar time) that takes into account the advantages of both long-term stability of pulsar time and short-term stability of atomic time.

Digital Satellite TV Timing System Successfully Switched TV Satellite
Recently, digital satellite TV timing system, proposed and established by the National Time Service Center(NTSC) of the Chinese Academy of Science (CAS), has successfully switched TV satellite. The timing accuracy after switching is basically the same as that before, is less than 50ns (RMS). The switching of TV satellite further verifies that the digital satellite TV timing system has better timing service capability and timing accuracy.

70th Anniversary of Beiing Time---Low Frequency Time-code Time Service Station
The National Time Service Center (formerly Shaanxi Astronomy Observatory) began to study the low-frequency time code timing technology in 1993. In 1999, a practical test platform was built in Pucheng, Shaanxi Province. In 2007, a high-power low frequency time-code time service station was set up in Shangqiu, Henan Province, the call sign is BPC.
