NTSC Researches Made Important Progress on Time-keeping Theory and Method
Recently, Metrologia, a leading international journal in the field of time frequency, published the academic paper- Detecting an atomic clock frequency anomaly using an adaptive Kalman filter algorithm co-authored by Mr. Song Huijie, Dong Shaowu and other members of the Key Laboratory of Time-frequency Standard of National Time Service Center (NTSC), Chinese Academy of Science (CAS). The paper is significant for keeping China’s time reference. It marks that NTSC researches on time-keeping theory and method have gained international recognition.
In recent years, NTSC has been contributing to improving the performance of the national standard time, developing methods to evaluate atomic clock performance, carrying out innovative researches onintegrated multi-links GNSS time transfer methods and applications of reference clocks to time-keeping systems. Breakthroughs have been made in time-keeping methods and technologies, as well as researches on GNSS time transfer.
