have you run this mod? with the "quality" of the map and the measurement devices, you'll be lucky to know which box you're in...
I wasn't going for super-accuracy, I was just seeing if the stars are in the right place for the longitude

Postalbyke,can you make it more precise?

postalbyke · 07-29-11, 07:55 PM

I'll have to look around for the location of the night sky after my daughter goes to bed... and my wife gets home from work lol

edit: haven't found the night sky yet, but I have found the sky...it looks like the sun and the moon live in the center lol

postalbyke · 08-02-11, 08:50 AM

update: Still haven't found it... and no hints yet from anywhere else... *sigh*
think it's in the exe...

edit:
I'm sorry guys, I'm giving up for now...

I do not fully understand your question but maybe this will help.

-If you do not understand simple dead reckoning read up on it elsewhere.
-If you do then read all threads here starting at beginning, "most" interface
questions will be answered.
-read all instructions in real nav mod.
-Do not worry about being confused.
-Go on simple cruises, plot courses to get used to all interface actions.Time
versus speed calculations. Steering by compass or rudder, speed over
ground, sleeping past your watch ex.This is to learn differences of
simulation from reality.
-Do not pursue or be pursued until you are confident.
-Increase length of cruising in all conditions and depths to understand what
can be expected.
-When ready apply the sextant learning.
-Be patient and try to think simple about the process.

This makes Plotting and verification simpler for global navigation.It does for
me at least.

Hi,

I'm trying to locate a copy of theses mod files. I can't get any of the links to work throughout this thread. Does anybody have a copy they would be willing to share?

Thanks
Didd

Didd · 12-17-11, 03:25 PM

As soon as I ask for help I manage to find it myself in one of the stickies. I've been trying to find this for days. Still at least I've got it now.

How can i use real navigation when there is no longitude/latitude-reference on the map? I mean everything of a sun-, star-, moon- or whatever-shot comes down to a longitude/latitude-position. So how can you determine for example the exact(!) position of 53°34.14'N, 005°14.03'E on a GWX SH3-map?

Didd · 12-21-11, 02:01 AM

Part of the mod files contains a map with lat and long marked on it. It's fairly coarse mind marked in degrees, so at best with measurement and subdividing, I've been able to plot degrees to one decimal place (6 minutes) which is more than close enough really. I doubt my "fixes" are as good as that anyway.

don1reed · 12-21-11, 07:34 AM

@ CaliEs:

Those alternating white/black hacture marks located around the perimeter of your in-game chart (F5 screen) are the Latitude and Longitude. They remain unlabeled to this day; however, you can use the prime meridian and your home port as starting reference, by counting them as your voyage progresses.

Cheers

@ don1reed:

I have only just started trying to use SH3 in any sort of real navigation way. I also came across this problem. I considered plotting my position 'by eye' from another map, or using the KM grid converter backwards by trial and error. This was the main reason for me downloading these mod files.

What I found was that those black/white marks on my map seem to correspond to the scale bar in the bottom left corner and remain a constant physical size when the map zoom changes. They do not seem to correspond to the lat/long marks contained within these mod files.

I realise that you have been operating this way with success for some time - indeed it was your posting here that provided the inspiration for me to try it myself and would be interested to know how you plot you lat/long position onto the SH3 map.

Thanks

Happy Winter's Solstice, everyone.

1. Let me (highly) recommend:

http://www.amazon.com/Celestial-Navi.../dp/0070059284

For anyone interested in Celestial Navigation.

It's cost is minimal ($10.25 USD) and can be purchased through the Amazon link (above, right) it will help SUBSIM.

2. You Cannot use the DISTANCE = SPEED x TIME formula with F5 chart in the game. (Reason: the F5 chart is not a Mercator Projection chart.) The Devs use their F5 chart to suit their game engine to make this whole thing work. Because of this you cannot accurately predict or work out a Running Fix for a Day's run, or Etmal (noon to noon) run...

HOWEVER>>>

you can use STAR, MOON, & PLANET fixes to find your Geo Coord. to connect the FIXES to fashion a course.

3. The White and Black, alternating, Hacture marks ARE the Latitude and Longitude of and for the game. They measure 120km x 120km, trying to emulate a square degree of 60 nm x 60 nm. It follows, then, that every 2km = 1 nm. Zoomed in, you must use "Sailor's Eye" to determine decimal parts.

4. If you use the "Python/Stellarium" method of navigation, you notice that this method uses the game's engine formula to determine your position at sea. To fully immerse yourself in the WWII navigation experience, playing TC x1 will do the trick.

-...-

Back in the day, when Celestial Navigation by Sextant was still being taught at Annapolis, MD., USNaval Academy, 0.5 nm Fixes was expected...nay...demanded.

Doing the Midshipman's dance on the heaving quarterdeck of HMS Surprise with Jack Aubrey in some un-likely sea to find Noon, puts me to sleep each and every night.

"Dammit, Lad, there's not a moment to lose!"

So real navigation in SH3 is incompatble with zoom-level 1?

Can't find any script in the vanJast-files. Where can i get this script?
