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.

    Honestly, we should all be sore about the Normal Conquest. It made us know French words.

    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.
