A new atomic clock is one of the world’s best timekeepers, researchers say — and after years of development, the “fountain”-style clock is now in use helping keep official U.S. time.

New Atomic Fountain Clock Props Up the World's Time With Pinpoint Precision Learn about NIST-F4, the latest cesium fountain clock that now stands as one of the most accurate timekeepers in the entire ...

Analog clocks are being replaced by digital versions, including in automobiles. Very rarely will you see an analog clock on a dashboard, but there are still companies out there that use them.

The advantage of a radio-controlled clock that receives the time signal from WWVB is that you never have to set it again. Whether it’s a little digital job on your desk, or some big analog wall ...

Atomic clocks keep getting smaller, lower power, and better—Microchip’s latest chip-scale version leverages EXMO technology to bring its height down to half an inch.

A technological innovation could revolutionize the precision of navigation systems. A tiny device, shaped like a comb, promises to deliver unparalleled accuracy in the field of positioning.

A radio-controlled clock has a radio inside, which receives a signal that comes from a place where an atomic clock is located, so they are always accurate, according to the National Institute of ...

A low-noise chip-scale atomic clock (LN-CSAC), the SA65-LN from Microchip, features a profile height of less than 0.5 in. (12.7 mm). Aimed at aerospace and defense applications where size, weight, and ...

The next generation of atomic clocks "ticks" with the frequency of a laser. This is about 100,000 times faster than the microwave frequencies of the cesium clocks which are generating the second ...

Atomic clocks that excite the nucleus of thorium-229 embedded in a transparent crystal when hit by a laser beam could yield the most accurate measurements ever of time and gravity, and even ...
