Scientists are exploring a new type of optical atomic clock based on ytterbium-173 ions that could help define the future standard for measuring time.

China has built a tiny, highly accurate atomic clock that could boost drones, missiles and satellite navigation, highlighting how precise timing is becoming crucial in modern warfare systems ...

Nuclear clocks are the next big thing in ultra-precise timekeeping. Recent publications in the journal Nature propose a new method and new technology to build the clocks. Timekeeping has become more ...

To find out how clock accuracy is verified and which reference is used for comparison, we visited the Belarusian State Institute of Metrology (BelGIM), where most of the national standards are kept.

Atomic clocks are key for satellites being able to provide positioning data that is used for applications such as navigation ...

This is the third time that the clock has been moved closer to midnight in the past five years. “Every second counts, and we are running out of time. It is a hard truth, but this is our reality,” ...

A sudden atomic clock failure on March 13, 2026, disabled a key NavIC satellite within minutes, prompting concerns over India’s GPS alternative and its long-term performance. This event has made ISRO ...

Launched aboard the PSLV–C32, ISRO’s workhorse, and successfully placed into geosynchronous orbit on March 10, 2016, it was ...

IRSO's NavIC system faces challenges as the last atomic clock fails, reducing operational satellites for navigation services.
