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 descended ...

In the world we live in, time is far more than just the clock on the wall. From financial transactions to power grids, from communication stations to scientific research, the efficient collaboration ...

The US Air Force is advancing efforts to enable drone swarms to operate in environments where satellite navigation is denied ...

DENVER (KDVR) — It is said that time is relative and passes differently depending on an observer’s relative motion and gravitational potential. Although some would argue time is a construct, it does ...

Timing — the unglamorous yet essential T in PNT (positioning, navigation and timing) — has been called “the invisible utility.” In fact, it’s been a long time since we last put a GNSS-timing receiver ...

Atomic clocks use quantum physics and the resonant frequency of atoms, like cesium, to define time. Modern timekeeping relies on the accuracy of atomic clocks, which revolutionized timekeeping by ...

The application of GPS time series analysis in geophysical modelling has transformed our understanding of Earth’s dynamic processes. By continuously monitoring displacements at the millimetre level, ...
