Improving the Efficiency of Control and Reliability of Time Scale Generation for a Group of Hydrogen Time and Frequency Standards

The article discusses the subject of generation and keeping of time scales. The frequency of intragroup monitoring of the rate of hydrogen masers is singled out as one of the factors affecting the reliability of the generation of the time scale. A new algorithm for the generation of an analytical and physical time scale for a group of hydrogen masers is proposed, based on increasing the frequency of intragroup monitoring for the course of hydrogen standards. Using this algorithm, the identification and compensation time for the variations in the rate of individual hydrogen standards was reduced from 1 day to several minutes. The analytical group time scale formed in accordance with the algorithm proposed provides detailed information about the variations in the rate of individual hydrogen standards during the day. It was revealed that variations in the rate of separate hydrogen standards and the error of the time-interval counters contribute to the instability of the physical time scale. On the Russian State primary standard of units of time, frequency, and national time scale GET 1-2022, it was experimentally confirmed that by increasing the frequency of intragroup monitoring in accordance with the new algorithm, the instability of the time scale formed for a time interval of observation >1 h is reduced.
