  • In this paper, through the establishment of a satellite common-view atomic clock discipline device, the local atomic time is compared with the national time and frequency reference station. Results show that the standard deviation of the rubidium clock is 2.19 ns, the stability of time deviation (1 day) is less than 1×10−9, the relative frequency deviation is −8.42×10−17, the frequency stability (1 day) is less than 2×10−14, and the discipline standard deviation of cesium clock is 1.5 ns. The stability of time deviation (1 day) is less than 1×10−9, the relative frequency deviation is 7.03×10−17, and the frequency stability (1 day) is less than 1×10−14. The local atomic time is effectively traced and provides technical validation to improve the verification system table of the time standard.
