Abstract
This article presents the project of creating a composite clock, the advances in its realization and the technical choices. The goal is to generate an output signal which combines the advantages of each clock, the long-term stability for the cesium clock, the midterm stability for the hydrogen maser clock and short-term stability for the VCO. The control system must keep the stability of the best clock within each duration range. This system is designed for reaching a relative instability of some 10 −14 @ 1 s, 10 −15 @ 10 3 s and 10 −14 @ 10 6 s at 100MHz, depending on the stability of the master clocks.
