Abstract :
We present the algorithm developed for locking a VCO to HM clock and to Cs clock in order to provide a very stable system having: the mid-term performances of the HM clock, the long term stability of the Cs clock and also the VCO´s caracteristics at the very short term. So it´s called composite clock.
