Atomic Time

The latest changes in the algorithm for the formation of the international atomic time scale TAI are reported in terms of estimating the weights of the clocks involved in the formation of TAI. Studies of the characteristics of the long-term instability of new-generation hydrogen masers based on processing the results of the clock frequency difference with respect to TAI are performed. It has been confirmed that at present, new-generation hydrogen masers show significantly less long-term instability in comparison with quantum frequency standards ofsimilar and other types.

The Stability

In the article, two models of instability of quantum frequency standards (QFS) are considered. This is a generally accepted stochastic model that describes the effect of noise with different frequencies on the stability of the clock and the simulation model proposed by the authors of this article, based on the Monte Carlo method and a software random number generator. Based on simulation results, a comparative analysis of advantages and disadvantages of the proposed QFS model in comparison with the classical model was carried out. The results of modeling, which showed good convergence with the accepted theoretical assumptions, are presented. The rationale for the feasibility of using the proposed model in the processing of navigation measurements is given. The possibilities of increasing the accuracy of synchronization of remote sets of reference time are shown.
