In this paper the new algorithm for the prediction of EAL (Echelle Atomique Libre) is presented. The effect of the application of the new model for the prediction term on the EAL frequency drift is quantified and presented together with its effect on TAI and on the atomic clock weights.
As it has been reported during EFTF'05 meeting on 2004, December 30 the realization of UTC(SU) - the national time scale of Russian Federation - was changed. We continue to maintain autonomous atomic time scale TA(SU) without any changes and started new realization of the steering UTC(SU). The main aim of steering time scale is to generate UTC(SU) as close as possible to the UTC and do not spoil considerably...
