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

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.

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 ...

The European Space Agency (ESA) has launched one of its most precise science experiments to date — the Atomic Clock Ensemble in Space (ACES)—to the International Space Station (ISS). This is no ...

Researchers demonstrated a new optical atomic clock that uses a single laser and doesn't require cryogenic temperatures. By greatly reducing the size and complexity of atomic clocks without ...

An optical lattice clock embedded in the curved spacetime formed by the earth’s gravity. Dynamical interplay between photon-mediated interactions and gravitational redshift can lead to entanglement ...

To measure time, you need a constant rhythm. For eons, the regular movements of the sun and moon have set the pace for all of life on Earth. But over millennia, humans have sought and found more ...

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