WebIt is a harmonic oscillator that uses gravity to swing back and forth, and this motion helps the clock keep time. Well, the natural way that atoms oscillate works similar to a pendulum in an atomic clock. Yet, atomic clocks are more precise because natural atomic oscillations happen at a higher frequency and as a result they are more stable ... WebHow does it work? From Microsemi: The MAC is a passive atomic clock, incorporating the interrogation technique of Coherent Population Trapping (CPT) and operating upon the D1 optical resonance of atomic Rubidium Isotope 87. A rubidium clock is basically a crystal oscillator locked to an atomic reference.
