An atomic clock is a device that measures time using the microwave signal emitted by atoms – or the electrons in atoms – when they change energy levels.Did you know atomic clocks only have an error of 1 second in a span of about one-hundred million years? This makes them one of the...

"The actual link is a loop." To test out their optical atomic clock idea, NIST researchers transferred ultraprecise time signals over the air between a laboratory on NIST's campus in Boulder, Colo., and nearby Kohler Mesa. (Image credit: Talbott/NIST) The test was done across land, but...
Separate clock solutions were then combined and integrated to generate a mean timescale for the ensemble. Results for sampling times of up to at least several days indicate that such a timescale is even more stable than the one being used to steer the USNO Master Clock....
In today’s highly information-based era, time and frequency are increasingly important in the military and civilian fields and have become very important resources [1]. The atomic clock is the core part of the timekeeping system. Its performance directly affects the stability of the timekeeping ...
