Most clocks, from wristwatches to the systems that run GPS and the internet, work by tracking regular, repeating motions. To build a clock, you need something that ticks in a perfectly repeatable way.

Adelaide University researchers have successfully tested a new type of portable atomic clock at sea for the first time, using technology that could help power the next generation of navigation, ...

This breakthrough in precision timing is about the size of your fingernail and only loses one second every 30,000 years. Reading time 2 minutes This tiny cube fits on the tip of your finger and also ...

A new optical clock concept based on ytterbium-173 ions may help bridge two key strengths of modern atomic clocks: the extreme accuracy of single-ion systems and the stability of clocks that use many ...

Arduino has just announced the Arduino Matter Discovery Bundle (AKX00081), an all-in-one development kit designed to help users learn, prototype, and build Matter-over-Thread smart home devices ...

AURORA, Colorado—Lockheed Martin and the U.S. Space Force are testing several new technologies aboard the next GPS III satellite, including a new digital atomic clock. Current GPS satellites carry a ...

In the realm of first-world problems, your cheap wall clock doesn’t keep time, so you have to keep setting it. The answer? Of course, you connect it to NTP and synchronize the clock with an atomic ...

Researchers at the UK’s National Physical Laboratory (NPL) have created a tiny atomic fountain clock. It is only 5 percent the size of a normal one but keeps the same high-precision time. The clock’s ...
