The European Space Agency’s ACES mission could ultimately pave the way for a global network of atomic clocks that make these measurements far more accurate.

From space, ACES will link to some of the most accurate clocks on Earth to create a synchronized clock network, which will support its main purpose: to perform tests of fundamental physics. But it ...

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. Known ...

Four Lexus models feature an analog clock on the dashboard, and they are all either sedans or coupés. Analog clocks can be found in the Lexus IS, ES, and LS sedans and the RC coupé, which Lexus ...

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 wa… ...

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.

Radio-controlled clocks are available in digital and analog forms for your home or office, and many are not expensive. For example, you can find a desktop digital version for $18.99 on Amazon.com ...

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 ...

Researchers demonstrated a new optical atomic clock that uses a single laser and doesn't require cryogenic temperatures. By greatly reducing the size and complexity of atomic clocks without ...

In atomic clocks, an atom’s electrons are pinged with electromagnetic radiation at specific frequencies. Bursts of energy excite the electrons, pushing them into a higher orbit around the atom.
