| 英文摘要 | The study of time scale facilitates stable and reliable operation of time-keeping systems. Algos algorithm is a common method for calculating the time scale. Improving the stability of the time scale is an important issue in the research of time-keeping technology. In this paper, an optimization method of the clock difference data preprocessing in algorithm is proposed. We apply the theory of optimal weight to the calculation of time scale weight for improving the stability of the dynamic time scale. The proposed algorithm is called Improved Dynamic Algos-like (IDAlgos). We use the IDAlgos for joint experiments of cesium clocks ensemble, hydrogen masers ensemble, and hydrogen-cesium clocks ensemble, respectively. The results compared with Conventional Dynamic Algos-like (CDAlgos) show that i) for the case of cesium clocks ensemble, the short-term stability has been improved, the stability increased by 22.5% in 2 h and 20.8% in 4 h. ii) for the case of hydrogen masers ensemble, the stability increased by 18.3% in 1 h and 31.3% in 128 h, that is, both long-term and short-term stability has been improved. iii) for the clock ensemble combined of hydrogen masers and cesium clocks, the long-term and short-term stability has been greatly improved,among them, the stability increased by 64.6% in 1 h and 69.3% in 128 h. Consequently, the IDAlgos has obvious improving on the stability of the time scale |
