THE SECRET TO BETTER AIRPLANE NAVIGATION COULD BE INSIDE THE EARTH'S CRUST

Summary from the TLDR newsletter

Airbus' Acubed and Google spinout SandboxAQ are developing an alternative to GPS. Its quantum sensing technology is now inching closer to commercialization. The MagNav quantum-sensing device uses quantum physics to measure the unique magnetic signatures at various points in the Earth's crust. An AI algorithm is then used to match those signatures to an exact location. The technology could be a promising alternative to GPS in a time when GPS jamming and spoofing are on the rise.
