Find out what’s speeding up Earth’s rotation and why it may force timekeepers to delete a second ...

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 ...

This breakthrough in precision timing is about the size of your fingernail and only loses one second every 30,000 years.

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

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.

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

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.

Researchers say the fingernail-sized devices could help transform drone warfare and other fields where precise timing is vital Timing is everything in modern warfare, where even a nanosecond's delay ...

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 ...
