The system uses a network of satellites, each equipped with highly accurate atomic clocks, to broadcast signals down to receivers on Earth.

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

He worked to develop an atomic clock that is essential to global positioning systems and helped confirm a rare state of ...

The speed of Earth’s rotation on its axis is increasing. The result of the increasing speed of Earth’s rotation has come in ...

In the final analysis, by showing that 10 heterogenous clocks across three continents could agree with each other to within a ...

Global positioning systems that support mapping programs are a prime example of how basic science can lead to unforeseen but ...

The plan is simple: to develop a more secure alternative to GPS by enabling the portable use of new atomic clocks, rather than relying on signals from satellites in space that can be jammed.

The science behind why the Earth will spin just a little bit faster on July 9, July 22, and August 5, this year.

It features a lower profile height and operates in a wider temperature range, providing low-phase noise and atomic clock stability in challenging environments. Chip-scale atomic clocks (CSACs) offer ...

Researchers have 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 ...

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

India’s state-run space agency has built an atomic clock that will fly in an upcoming indigenous navigation satellite.
