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.

NTSC Scientists Propose a Miniaturized "Perfect Difference" CPT Atomic Clock

A research group from the National Time Service Center(NTSC) of the Chinese Academy of Science (CAS) proposed a miniaturized "perfect difference" CPT atomic clock. The research shows that the coexisted electromagnetically induced transparency (EIT) and absorption (EIA) of clock transition signals in the new scheme, and the signal-to-noise ratio of differential CPT signals is greatly improved with a high-quality factor, which provides a feasible way to implement compact and high-performance CPT atomic clocks.
