氫原子鐘的頻率駕馭算法研究
[Abstract]:Using hydrogen clock as the frequency source of the master clock system, the local UTC (k), hydrogen clock with better short-term stability usually has frequency drift effect, which makes the long-term stability of hydrogen atomic clock decrease with the passage of time. Furthermore, the stability and accuracy of UTC (k) are affected. In order to solve this problem, the performance of hydrogen clock and cesium clock are compared and analyzed, the algorithm of hydrogen clock participating in time scale calculation is improved, and the frequency control algorithm based on master clock is proposed. The algorithm is tested by building the test system and compiling the related software. The experimental results show that the short term stability of the reference time scale can be improved effectively when the hydrogen clock is involved in atomic time calculation, and the local time UTC (k) generated by the main clock frequency source is better than the local time UTC (k) produced by the main clock frequency source is cesium clock.
