Abstract

The traditional atomic clock frequency prediction method has the characteristic of hysteresis which based on the clock frequency published by BIPM monthly. A dynamic prediction of atomic clock frequency model is proposed in this paper by using a rapid Coordinated Universal Time (UTCr) published by BIPM. The new method and the traditional method are applied respectively to the calculation of the atomic time scale in this paper. The time scale is calculated with the data of NICT, NTSC, NIM which participate in the calculation of International Atomic Time(TAI). The time scale calculated with the new method and the traditional method are compared with UTC-UTC(k), respectively. The result shows that the new prediction method is more available than the traditional method. It improves greatly the quasi-real time of frequency prediction, provides more quasi-real time and reliable reference for frequency steering and contributes to getting better stability and accuracy of UTC(k).
