The Cesium Atomic Fountain Clock Developed by NTSC was Licensed as a Primary Frequency Standard to Calibrate the International Reference Time

the Circular T 435 bulletin of the Bureau International des Poids et Mesures (BIPM) published the 18 consecutive months frequency data of the cesium atomic fountain clock (No. NTSC-CsF2), marking that the cesium atomic fountain clock independently developed by the National Time Service Center(NTSC) of the Chinese Academy of Sciences(CAS) is recognized to participate in the calibration of the international reference time scale (Coordinated Universal Time (UTC)), and starts to steer the International Atomic Time (TAI).

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.
