  • The time scale performance of different clock ensemble configurations is compared and analyzed concerning the technical specifications of atomic clocks. Simulations of hydrogen maser and cesium clock differential data were performed based on the technical specifications and actual operation of typical atomic clocks. The atomic time scales of the cesium clock ensemble, hydrogen clock ensemble, and combined hydrogen-cesium clock ensemble were calculated by applying the ALGOS algorithm, and the clock ensemble time scale performance was examined in four aspects: time deviation, time stability, frequency deviation, and frequency stability. The results showed that the frequency stability of the clock ensemble of 180 cesium clocks is equivalent to the frequency stability of 1 hydrogen maser. Due to the large difference between the frequency stability of cesium clocks and hydrogen masers, the weight of cesium clocks is much lower than that of hydrogen masers in the atomic time calculation process, and the contribution to the atomic time is limited. The clock ensembles with a high proportion of hydrogen maser have better time scale stability, and the time deviation and frequency deviation in the traceability state are also smaller. The clock ensembles with good time scale stability also have better timekeeping ability in the timekeeping state.
