This (or something similar) was done by someone with the SH3 version, and they claimed a 100m accuracy !!
I should make Cosine/sin Tables for manual calculations...
More later.

vanjast, you have used real celestial navigation and you know that even on dry land you're not going to get 100m accuracy (except by coincidence). At sea, 50 miles is considered a bullseye! That is why when navigating for a port, for instance, it is standard practice to know your expected error and aim to one side by a bit more than that. Then, when you encounter land, if you aimed south, for instance, you would know to turn right.
If you tried to hit the port dead on, you would be somewhere in the error cone and at landfall wouldn't know whether you were north or south of your destination. You'd have a 50% chance of turning the wrong direction! |
Yes, I know that, I'm just repeating what somebody else claimed in the SH3 forum.
As an example when I first tried the Mod in SH3, I had my last clear night off the coast of Norway, from there dead reckoning (DR) to Scotland. Sighted land without having a clue where I exactly was - working out an approx position, plotted a course to the outer western island of Ireland. After 2 weeks of gale force seas the sky cleared enough for a quick fix - course adjustment of 10degrees and a few days later spotted the island about 5 NM off the port bow.
That was my first Nav attempt - Now I hoped to have improved the accuracy in SH4, having read volumes on navigation, which is quite interesting.
