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?

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.

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.
