“Quantum sensors can sense the tiniest of changes in the gravity or magnetic field and use a previously prepared map of these properties to determine their location. Since a quantum sensor does not need to receive or send a signal to an external device, it cannot be hacked or be spoofed by a fake incoming signal either. “ Very cool!

*Cant be Non-magnetically hacked

I don't think it's realistically possible to do that totally undetected. Since the earth's magnetic field is so weak and field strength goes down rapidly as distance increases, malicious actors probably couldn't spoof patterns well enough to make the data look real, at least not without coming very close and staying near their target.

Cue magnetic mines, but where are you getting the gravitic mines from?

[–] postmateDumbass@lemmy.world 5 points 1 day ago

They just trigger degauss on 10,000 CRT monitors simultaneously.

If it works off tiny changes in gravity, a really big rock would work.

Our mission is to sneak this Ayers rock under the boat without being detected. In and out. 45 minutes tops.

[–] fartographer@lemmy.world 2 points 15 hours ago

And that rock? The moon.

Most people probably don’t know but we call it Uluru these days as that’s what the local Aboriginal people named it. Ayers Rock is the old coloniser name, and pretty out of fashion.

I know and I am sorry, but the joke would have gone over the head for most of the people if I had said Uluru.

[–] MalReynolds@slrpnk.net 22 points 1 day ago

I was going to say something about the scale of gravity changes needed, but your take is way better. Cheers.

Well, to be fair, a big rock would also work on a GPS device, if applied directly to it.

[–] Kanda@reddthat.com 3 points 1 day ago

Might as well just hit the ship with a really big rock at that rate

[–] echodot@feddit.uk 6 points 1 day ago

It's a bit obvious that isn't it. Hey captain there appears to be a ship with a giant boulder on board and it's following us around, do you think that might be relevant?

Ah time to make use of my massive tungsten cube

Just sell initially fake map
