Scientists proposed a time autonomous maintenance method with small step-by-step adjustment of the control strategy based on Autoregressive high-precision time difference prediction after a large number of experiments12 28, 2021
Currently for the accuracy of long-range time transfer can only reach up to 100 ps, limiting the wide application of high-precision time-frequency reference in space science. The study of the satellite-ground precise time synchronization method can provide an effective solution for developing long-range time transmission technology.12 27, 2021
Based on the strontium optical lattice clock platform, the research team led by Prof. CHANG Hong from the National Time Service Center, the Chinese Academy of Sciences and ZHANG Xuefeng from the School of Physics of Chongqing University observes the interference effect between Floquet quasi-particles.09 24, 2021
The national Science and Technology Award Conference was hold in Beijing on November 3 2021. Prof. WU Yuanwei from NTSC won the National Prize for Natural in Sciences (second class).
Researchers from the National Time Service Center of the Chinese Academy of Sciences recently completed the dam deformation monitoring system.
Recently, the journal evaluation report World Journal Clout Index (WJCI) (2020 Science and Technology Edition) jointly launched by the Institute of Science and Technology Information of China and other institutions was released, and Journal of Time and Frequency sponsored by the National Time Service Center was indexed.
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+
