Abstract
The issues of time scales keeping and generation are considered. The frequency of performing 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 a paper clock and physical time scale for a group of hydrogen masers is proposed, based on increasing the frequency of intragroup monitoring of the rate of hydrogen masers. As a result of using this algorithm, the time required to identify and subsequently compensate the variations in the rate of individual clocks was reduced from one day to several minutes. The paper clock formed in accordance with the new algorithm gives detailed information of the variations of the rate of individual hydrogen masers during the day. It is shown that both variations of the hydrogen masers rates and the error of the time interval counter, is contributing to the physical time scale instability. On the National time and frequency standard of Russia, it was experimentally confirmed that by increasing the frequency of intragroup monitoring in accordance with the new algorithm, the instability of the physical time scale for a time interval of observation more than 1 hour is reduced.
