Hmm sounds like it's using something like a SQUID (https://en.m.wikipedia.org/wiki/SQUID ) but as far as I know they all need to be cooled with liquid nitrogen; would be cool if they've invented one that doesn't
Since this relies on magnetic sensors, wouldn’t it be possible to jam with a magnetic field?
Curios how it would work with say planes, espcially if ionosphere is disturbed
Quite interesting, to myself magnetic fields wouldn't seem all that accurate but then again it's known some animals can navigate back to the same spot each yearly nesting / migration. It did seem maybe as per the article and [1] [2] the concept was just a little bit too good to be true but [3] being military supports that they've been working towards an additional perhaps more accurate system.
