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

Not sure about why the downvotes. You are correct. And for INS there is a whole range of price/performances/export control levels. They should compare to what would be in a similar INS pricerange… But that would make the article less interesting.
