Better than an atomic clock

Better than an atomic clock

An essential element for navigation is time. For navigation via celestial observations, you need to know your time down to the second. When we get into electronic navigation systems like GPS, second-level accuracy is not good enough. For that application, we need to start adding prefixes like milli-, micro- and nano- to seconds. The better we know time, the more accurate the navigation solution will be. And now the scientists and engineers are devising a new type of timepiece, called a nuclear clock, that will be the ultimate timepiece.  One of the great stories in the history of navigation was…
