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 ...

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.

The way time is measured is on the edge of a historic upgrade. At the heart of this change is a new kind of atomic clock that uses light instead of microwaves. This shift means timekeeping could ...

Physicists at the Joint Institute for Laboratory Astrophysics have developed a new atomic clock that is so accurate, it will not lose a second of time in more than 200 million years. That makes the ...

Considering that 90% of American adults own mobile phones, the practice of interrupting strangers to inquire about the time has almost completely disappeared. Since these devices are so prolific in ...

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

At this point, atomic clocks are old news. They’ve been quietly keeping our world on schedule for decades now, and have been through several iterations with each generation gaining more accuracy. They ...

India's indigenous satellite navigation system NavIC faces fresh reliability concerns after IRNSS-1F's atomic clock failure, ...

Andrei Derevianko, an associate professor in the College of Science’s Department of Physics, is part of a group of physicists who were recently featured on Discovery Channel for their work in the ...

The next generation of atomic clocks “ticks” at the frequency of a laser. That is around 100,000 times faster than the microwave frequencies of the caesium clocks that currently generate the second.

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