Optical quantum clocks developed at the University of Adelaide have been proven to outperform GPS navigation systems by many ...

The satellites that make the GPS in your car and smartphone work consist of many atomic clocks. About 400 such atomic clocks ...

On January 17, 2025, a Ryanair flight from London was just moments from touching down in the Lithuanian capital of Vilnius when its descent was abruptly aborted. The Boeing 737 MAX 8-200 had ...

“The optical clock community is strongly motivated to obtain the best possible set of measurements before the SI second is ...

Atomic clocks in current GPS satellites will lose or gain a second on average every 3,000 years. ACES, on the other hand, “will not lose or gain a second in 300 million years,” says Luigi ...

Atomic Clocks and Quantum Sensors Could Be the GPS of the ... Colorado-based startup is working on a suite of chip-scale quantum sensors that can serve as an alternative to satellite-based GPS.

There are hundreds of atomic clocks in orbit right now, perched on satellites all over Earth. We depend on them for GPS location, Internet timing, stock trading and even space navigation.

Earth is set to experience unusually short days in July and August 2025. The Moon's orbital position is subtly accelerating ...

GPS satellites are equipped with an extremely accurate atomic clock and know their positions at all times. They continually transmit the time and their location using radio waves.

GPS location, Internet stability, stock trading, power grid management ... all rely on atomic clocks in order to work. Many of those clocks are in orbit, perched on satellites orbiting Earth.
