Quantum nav... awww man, for a second I thought The Orville was back!

[–] rob_t_firefly@lemmy.world 16 points 3 hours ago (2 children)

The trouble with Quantum Navigation is you might end up where you were trying to go, but at a random point in the past where you have to change history to put right something that once went wrong.

As long as you keep it below 88 miles per hour you'll be fine.

And you'll never be able to return home too.

Perfect for autonomous military robots.

The only significant word here is "quantum". This stuff is too expensive to be useful for anyone other than the military right now. Gravity maps are controlled information as well. Used for ballistic submarine missiles. The maps created by the military will never be made public. (It would look like a highway of where every vessel is or will be)The accuracy of satellite measurements is 3km, with physical topographic (sea/land) resolution at 1.2km. The long-term plan is to have these sensors traverse areas, record data, and then share it with a database. Even those maps are realistically only 300m~ in resolution. Compare that to GPS, which has a nominal resolution of 3m with 15 satellites, or about a foot, with a correction from ground relays. (I remember using a handheld device that would tell you how many you were connected to, and it stopped working once you were near a tree.) Gravimeters have been used by submarines since the 1980s.

The Quantum Compass! Sick!

Wow, more AI. For some reason. This doesn't sound like it needs AI but the investors would pay less, of course!

Chances are AI is easier than hand-rolling an algorithm for this. And that AI is almost certainly not an LLM.

We really should still be calling this machine learning... Calling stuff AI has so many connotations that aren't really applicable to this type of software. We've had image recognition and other matching algorithms for years before LLMs came along.

Everyone seems to think all AI is the same thing which is NOT true.

The gravitational pull is stronger on the left side so you have to account for that or else you'll just sail around in circles. /s

[–] xthexder@l.sw0.com 1 points 37 minutes ago

The device also has to account for the location of your mom.

(sorry, I couldn't resist)

Easy to correct - just keep the Skipper in the center of the boat. Gilligan's pull is negligible.

Most sailors spend their whole lives sailing around in circles
