Atomic clocks are the basis upon which a second is defined. But there is a new kid on the block, the optical clock, which ...

A technological innovation could revolutionize the precision of navigation systems. A tiny device, shaped like a comb, ...

Tapping into the teeth of a comb Microcomb chips could change this by bridging the gap between high-frequency optical signals (which optical atomic clocks use) and the radio frequencies used in the ...

The size, power, and other metrics of a latest-generation chip-scale atomic clock.

Radio waves travel fast, and they can bounce, too. If you are able to operate a 25-meter dish, a transmitter, a solid software-defined radio, and an atomic clock, the answer is: yes, they can go ...

Atomic Digital Clock Auto Set (no back light) - Using radio frequencies broadcast from NIST’s Colorado , the clock will automatically set to the correct time. Automatically adjusts to Daylight ...
