Gsus4 comments on World's first GPS-free quantum navigation trial succeeds at sea

this article is better written:

https://science.report/discover/quantum-gravimeter-demonstrates-gps-free-navigation-in-coral-sea-trial-86654/

it maintained bounded position accuracy within 1 nautical mile over an 83-kilometer trajectory. This performance, achieved without access to satellite navigation, represents a more than tenfold improvement over standard navigation-grade inertial backup systems under similar conditions.

It also doesn't pretend the page failed to load when it detects an ad blocker.

Here is the real article without the compounding editorial errors.

Inertial navigation (INSS) and GNSS (Sat nav)is two completely different concepts. Too bad the article misses this. Perhaps AI hallucinations?

No, it's saying it works better than INSS, without resorting to GNSS.

That’s better, thank you

As a holder of a spatial degree I found it difficult to directly compare it favourably to GNSS. Even a simple binary code calculating a position with GNSS gives sub 10-20 metre accuracy, generally closer to 2 or 3.

I don't think it's meant to be better than GNSS in terms of accuracy, just better in terms of reliability because it works entirely standalone without a need for satellite

There have been lots of cases of GPS jamming lately, where this could be used as a backup. And even more crucial for certain situations, it could detect GPS spoofing attacks.

Yeah nah I understood that, the quote made in the initial comment implies somewhat that it does.
