Abstract :
The composite clock architecture we explored is composed of a VCO controlled by both a hydrogen maser and a cesium standard. We realized two composite clock prototypes: an industrial one (passive maser + commercial cesium) and another one suitable for metrological laboratories (active maser + high stability cesium). This paper describes the performances of both systems, from 0.01 s to 10 days.
