  • Abstract
    A new algorithm for the clock frequency prediction used to calculate the Echelle Atomique Libre (EAL) is presented. The mathematical model adopted in the new prediction algorithm takes into account the effect of the frequency drift of the H-masers. We demonstrate that there is an improvement in long-term stability of EAL by using the new prediction algorithm.
