A composite clock layout and results are presented. This apparatus combines the stability of several reference clocks for different durations. A voltage-controlled quartz oscillator is driven by a hydrogen maser clock for mid-term stability and by a caesium atomic clock for long-term stability. The best clock stability at a given averaging time is transferred to the voltage-controlled oscillator by a special control system using two commands.

Inspec keywords: caesium; voltage-controlled oscillators; atomic clocks
