The study of using hydrogen maser ensemble to steer UTC(TL)

摘要

For steering UTC(TL) during the latency period between UTC monthly announcements, we create a paper clock generated from a hydrogen maser ensemble according to the weekly published UTCr. The frequency of hydrogen masers are modeled and predicted as a linear function calculated from the linear regression of hydrogen masers vs. UTCr. The hydrogen masers with closer predictable frequency will be given more weight to constrain the paper clock follows the frequency trend of UTCr. In the paper clock simulation test, neglect the phase error accumulation affected by each frequency prediction error, the phase difference of 10 days prediction span between the paper clock prediction and official time scale are from -4 ns to 2 ns.
