Publish Time:2019-03-31
The atomic clock frequency drift calculation period of the BIPM atomic clock is one month. Theatomic clock frequency drift calculation results corresponding to the Julian days of the previous month are published at the beginning of each month, in ns/day/30days. Among them, the serial number of the clock corresponds to different types of clock. Among them, 35- represents cesium atomic clock and 4x- represents hydrogen atomic clock, which occupy the vast majority of the clock types. In addition, there are other clock types. The NTSC obtained the atomic clock frequency drift value of the atomic clock in the laboratory by matching the data dictionary.
