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.

For decades, atomic clocks have provided the most stable means of timekeeping. They measure time by oscillating in step with the resonant frequency of atoms, a method so accurate that it serves as the ...

A new comb-like computer chip could be the key to equipping drones, smartphones and autonomous vehicles with military-grade positioning technology that was previously confined to space agencies and ...

On 13th March 2026, the procured on-board atomic clock stopped functioning. However, the satellite will continue to function ...

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.

Time is almost up on the way we track each second of the day, with optical atomic clocks set to redefine the way the world measures one second in the near future. Researchers from Adelaide University ...

As if timekeeping in the U.S. wasn’t already pretty accurate, the U.S. Department of Commerce’s National Institute of Standards and Technology (NIST) just declared a new atomic clock, the NIST-F2, to ...
