I've moved it even more to the left but still can't subtract 1° and not so sure about those numbers. Using flak camera doesn't change anything. Maybe I'll try 75° verstion. However getting my lat from ctrl-click and Vans map in SH3 i get 2,5°W instead of 4°W... so I'll just keep on plotting and enjoy flat sea, cloudless sky not worrying about sextant and try to sink something using slide ruler (great thing)!

This is still a little bit strange. On my current patrol it seemed as I had to hold the sextant a bit to the left to get an accurate reading and as I travelled ~10° north it was good again.
Also, in bad visibility the longitude method gets something inaccurate (the measurement was about 2° off).
But that wouldn't be all unrealistic because it should be very hard to determine the exact time of your local sunrise if you can't see the sun because of clouds and fog

.

Then I decided to just let it go with ctrl+click and do the best I can to navigate and see where I get with that.
I soon got a contact report for a large convoy SW from GB because of the heavy fog I have to approach it very carefully to not run into any escorts but I'm almost there.

I finally installed RealNav this weekend. I was at the end of a patrol on the Spanish coast in March, 1940, and decided to dock at the ship named Bessel for resupply. I installed the files for RealNav, the camera.dat file, and the mod that removes the tails of radio contacts.

I have to say that this is very interesting using the sextant on Polaris and interpolating the SR/SS times. I noticed it was very accurate at the beginning when I was leaving Spain. However, I started to get errors of around 60nm while heading toward 15 degrees West. I have found that Polaris is about one degree below what it should be on my screen (1280/1024). But I believe what is getting me bad results on the longitude readings is that the sun is coming up and going down too soon for the area I'm in. I parked the sub right on the 15 degree line (using CTRL-click) and I still was getting a difference of about 51 minutes between my sun set and the GMT sun set reported on Van's almanac (instead of the expected 60 minutes).

I need to play around with it some more to see if I can find any consistency with the times so that I know if I should add a couple of degrees here and there to match the game map.

Thanks,
Ron

Congratulations for installing

The sunset times seem to be a good bit off. Better use the sunrise times. I think you already read it bould you also should use the red-light-off point as your local sunrise time.

All in all it seems like the real navigation is a bit inaccurate because it depends on many factors as time measurements, average speed calculations and estimated distances. And everything is influenced by the weather.
But it's still a fun way to play

Kumando · 07-04-07, 05:38 AM

I would really like to try this mod because i love manual navigation, i already navigate manual but with Dantenocs method but this one seems more interesting . The question is can you use the sextant at sunrise, noon and sunset or only at night with the stars? If its possible can someone make me a quick tutorial to learn it?

Thanks in advance.

ichso · 07-04-07, 06:21 AM

Hi Kumando,
I THINK I read somewhere that you can shoot also the sun and moon with the sextant. I'm pretty sure I read that but don't know where. I tried it once just for fun but got nothing out of it and forgot about it. As you asked I will check again if it was in the manual that came with the mod.

Hi Herr Kaleun,

As you can see it, this is my first post here, nonetheless I'm an old player with a very personnal and heavy modded stock game.
I take the opportunity to tell my gratitude to all the modders and the people of this forum for the incredible amount of work they did.
If I never posted that's because I allways found the answers to my questions...

But....with this marvellous tool that is RealNav, for the first time I'm facing a problem I can't solve. To make it short : How do you know with precision (I mean to the degre at least) what is your current course heading?
The dials provided, especially the compass is far to rough for a fine reading. The only solution I managed to find is to use the free indoor cam to look closely at the compass behind the CO.
But it's not really playable, and not very precise.

Has anybody a solution?
Thanks

Hi and welcome !

To answer your question shortly: Yes

What you are looking for is to be found here:

Hope this helps. Be careful installing it though it introduces many changes to the menu_1024_768.ini.

Greetings, i.

I thought id post this here as this is a problem it seems related to the real nav mod/s albeit a small one. My recognition manual dissapears when i play sh3 only parts of it appear, why is this? it seemed to be okay until i installed real nav mod and the real nav fix which gets rid of the marker/guide which gives away your position, i think one or the other has caused this problem, but i want to play with both mods what do i do, hopefully im wrong and neither mod is causing the problem. HELP!!!

divingbluefrog · 07-05-07, 05:06 AM

@ Ichso
Thanks for the answer. You put me in the right direction.
I managed to find the original mod by EX_Rasinban. But I'm not satisfied by the look of the compass. As you can see here :
http://ubootwaffe.net/u505/cr_hs.html
the compass used in U-boot was quite sober. I'm still working on an improved version.

This would be great. I never really cared yet since the compass in this mod looks very sweet.

I never installed the RealNavFix but still without it I see no tails at the map contacts. Perhaps you installed the wrong version of RealNav ? E.g. an older one that isn't compatible to GWX ?

divingbluefrog · 07-05-07, 09:34 AM

So DUMB we are!

Did you ever wonder what was the purpose of the dashed, zoom sensitive, lines on the borders of the map?
We have it right in the front of our noses and never got it....
So.....NO!?....Really?!.....Meridiens and Parallels of course!

You don't believe me? Just go to the cross point between the AN26-AN21's limit and the Greenwich meridien. Yes, you are on the 60 N and 0 W point.
You can find another references as well : vetical limit between AM and AN grids on their north part fit the 5 W....and so on.
So now you can draw your own parallel and meridien lines everywhere in the world!...Nice, isn't it...

And with the most precision due to the level of zoom you choose.

Another tip : After having set a course heading, wait a little to be sure you are on the straight line and then hit rudder amidship. This should help the helmsman to stay alert during the course.

buahahahhaa :rotfl:

yeah, I want comment on this one

btw I've tried rudder amid and didn't do anything to keep course...

divingbluefrog · 07-07-07, 09:59 AM

Well, it's done, for the most part.

I have now a fully functional compass, with + 0.5deg precision.

Taken just after out of the pen in Bergen.

As an help, I put a listing of the meridiens and parallels' scales in the map window.

If you don't mind editing your menu_1024_768.cfg, you could move the block given by Kaleun Freddie for the sextant to the G34 group (you'll need to change the ParentID for that of the group) and then, the sextant will be only available in exterior view, as it should be, IMO.

Im also thinking of having an access to the SS/SR chart in game, but I don't know if I could succed in such a try....:hmm:

ichso · 07-07-07, 11:46 AM

What does that little notepad on the last picture show ? Shows it the latitude and longitude under the cursor position ? That would be great to make some more precise drawings on the map for real navigation.

divingbluefrog · 07-07-07, 01:38 PM

No, it doesn't. It's just a memo that tells you what is the scale of the meridien tab at the current zoom : here 50km so 05' per dash.

I think Kaleun Freddie was to hard cutting the zoom levels. I find that if you only cut the three first, you still get a 2500m zoom which gives you a 15" resolution, whithout showing you the position of your sub. That's how I find that the exaction longitude of Bergen is 8 18' 45" E (entry of the pens).

I also managed to include the SR/SS chart in game, but as free sheets, one page per month, and not as a book which was my first thought. After all "do it simple"...
