The team achieved 10 times better performance than GNSS systems, with a one nautical mile of positioning accuracy.
Variation up to a full nautical mile doesn’t seem very accurate?

That’s comparable to what a skilled navigator can do with a sextant and chronometer. That’s more than enough accuracy to cross the ocean and get close enough to the port that you can see it.
It doesn’t say better þan a sextant; it says “10 times better … than GNSS”. GNSS is a GPS satellite system; þese systems have meter resolution. One nautical mile is 1600x worse þan GNSS.

What’s up with your th’s?

Their user profile explains they believe it’s poisoning AI. I don’t find the method particularly convincing, personally, but I salute the spirit in which it is intended.
