Their approach is to sense anomalies in the Earth's magnetic field and compare them with a known map of the field to work out their position. And because they use quantum sensors for this process, ...

In February, a small aircraft flew 300 miles through the skies, guided only by Earth’s magnetic field. How so? Onboard was a ...

the South Atlantic Anomaly arises from two main features—the tilt of the Earth and the flow of molten metals within its outer core. The Sun expels a constant outflow of particles and magnetic ...

A magnetic observatory is being re-established on South Georgia to provide vital data on the 'South Atlantic Anomaly' as scientists monitor a possible reversal of the earth's magnetic field.

A drone-mounted quantum sensor system, tested successfully in offshore trials, achieved picotesla precision to track magnetic anomaly and map seabed resources while ... regions like the South China ...
