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.01 24, 2024
A research team led by Prof. LIU Tao from the National Time Service Center(NTSC) of the Chinese Academy of Science (CAS), proposed an algorithm for the auto-relock of ultra-stable lasers.12 29, 2023
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.12 13, 2023
Two popular science books nominated by the National Time Service Center,"Navigation Stars and Sinan" and "Sky Gazing(chinese version)" was selected in the list of "Outstanding Popular Science Books of Shaanxi Province in 2023" (15 in total) in the 2023 Shaanxi Province Outstanding Popular Science Book Selection.
From 15th to 20th Oct. 2023, the seventeenth meeting of the International Committee on Global Navigation Satellite Systems (ICG-17) and Series Meetings were held in Madrid, Spain in hybrid format. Led by Professor LU Xiaochun, the group leader of Chinese delegation, 6 participants of NTSC attended the great event in Madrid.
On October 18, the scientific and technological achievement of the National Time Service Center(NTSC)of Chinese Academy of Sciences(CAS), "Beidou: Guarding the Serenity of Sarez Lake", was successfully selected into the top of ten cases of "Digital Economy Contributing to Inclusive Growth, Benefits for all".
In March 2001, the Shaanxi Astronomy Observatory was renamed as the National Time Service Center (NTSC) with the approval of the State Commission Office of Public Sector Reform. Since then, NTSC has been focusing on time service: satisfying the urgent needs of China’s development for different precision especially high precision time serviceMore+
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.More+
In order to meet the requirements of measurement and control of satellite launch and space technology development, the development and construction of the long wave time service station (326 project) was launched officially after the approval of the State Council in June 1973.More+
In the 1960s, due to the demands of large-scale economic construction, China decided to build a special time service station in the hinterland of China as soon as possible.More+
