Atomic clock

An atomic clock provides more accurate time

Many of the great technological advances of the last fifty years have depended heavily upon timing devices. From aerospace and defense to telecommunications, and from enterprise networking to energy, highly sophisticated technology frequently relies on the ability to keep extremely accurate time. In recent years, the atomic clock has emerged as one of the world's most accurate precision frequency references. An atomic clock uses the resonance in the hydrogen, cesium, or rubidium atom as the basis for the stability and accuracy of an output reference signal. When leading enterprises and manufacturers today seek superior and affordable atomic clock technology for their timing and frequency devices, they turn to Symmetricom.
