Calculating AOB with OLC Gold

BenG · 05-25-09, 02:08 PM

Preface: I was previously using GWX 2 and an "earlier" version of OLC GUI. (I can't remeber which version but the graduations horizontal graduations went 0 - 5 - 10 - 15 - 20).
I've now done a Fresh Install of SH3, GWX 3 Gold, Sh3 Commander & OLC GUI Gold.

The Problem: Now the graduations have gone to 0-10-20-30-40 I can't seem to calcute AOB.
In the following example:

•I've measured the range (using both the OLC scope wheel thing and with Map Contacts enabled). I make it 1,500 metres.
•I've aligned 1,500 (15) on the outer-part of the middle ring with the ships length (140.5m) on the Outer Ring.
•In the above example the ship is at approximately 26 horizontal marks.
•Now (this is the problem) 26 on the inner-part of the middle ring is well past 90 (°) on the Inner Ring??????

My Question(s)
1 - Am I doing anything wrong?
2 - Is there anything else I need to do to calculate the AOB (e.g. Halve anything or double anything).

There was an updated part of the tutorial.I guess OLC himself would come by soon and will tell you what you are doing wrong.

I also use OLC GOld though i measure the AOB on eye with good results.

you didn't do anything wrong Beng.the problem is that mast's values sucks and this have as result your range measurments to be tottaly incorrect.
open data\Sea\NKLS_ and there open the cfg file.set at mast=21.2 and save the file.your hot spot of the ship is the top of the funnel .here:

play again with this ship and see the results

bye

BenG,
You may want to read this page and then download the video tutorials. Note that the text on the linked page explains the "new" UZO markings (which aren't covered in any of the videos).
Regards,
OLC

Markman, where did you get 21.2? Do you have a list of correct mast height values?

hello Jmr,

i calculate it. no, i don't have such a list. i had only fixed 7-8 ships lengths and masts(which are the ships i am using in my missions).in fact , ALL OF THEM need corrections but this is impossible to be done by one person becuase the procedure for fixing one ship is a real pain !
note that i am using ''GWX_ships_Buoyance&draught_mod'' which is 'puting' the ships a little deeper in the water so the 21.2 is correct only if you are using this mod(if you not ,then it is a little bigger-about 0,5-1.2m-but i never tested it without the ''GWX_ships_Buoyance&draught_mod'' )

bye

I guess this was going to be my question. How did you know that ship is 21.2? How did you calculate it? How would you know what the other ships are? You can go in and change that file, but how do you know what to change it to?

Also, how did they get screwed up from the stock version? IF all the ships are screwed up, how does anyone calculate AOB? Usually I just take a rough guess if I get a ship that is off.

Well, you could have figured that out by reading the thread title, and the rest of the messages in it. (atleast a bit)

Sorry, I'm grumpy as my PC died on me today.

Those things around the periscope view are sliderulers to mimic/simulate the real-life german (attack) periscope optics that could determine both range and AOB in almost one go. Onelifecrisis made that mod you see here (it appeared in various editions, but his latest is OLC Gold Mk2b). They are also in the U-jagd tools by Joegrundman, and some derivative mods by others.

Those colored scales around the chronometer are scales to determine speed of a target, as they pass the line of your periscope. The full procedure is a bit more involved than just looking at the target though. (you need to eliminate the effect of your own speed) The colored circles represent a certain length of the target. After the needle has moved X seconds it points to the appropriate speed for the length of that color (100m, 150m or 200m). If the actual ship has a different length you need to chose the color that best fits, or multiply/divide appropriately. But I found a way to (ab)use that range/AOB finder wheel in calculating the speed for any length of ship. See that crooked mark next to the 60 degrees in the inner (AOB) scale?

Watch those videos in the link OLC gave above to see how they all work.

BTW, Does that mean we can start to corrupt you into the wonderfull world of manual targeting?

tmdgm · 05-27-09, 08:18 PM

ben,

did any of this help? I have had the same problems multiple times. some ships are ok, others aren't, but always the exact same, AOB >90. I posted the same question in the mods section, never figured it out.

onelifecrisis · 05-28-09, 04:02 AM

makman94 explained the problem. Its old news. Some modded ships have the wrong mast and length values. Would be nice if someone could be bothered to correct them all!

tmdgm · 05-28-09, 06:59 PM

is there a list of ships with wrong mast values?

did you try what i told you there Tmdgm or not ?

ps: oh,there is not such a list you are asking for

Sea Hawk · 05-29-09, 02:13 PM

Sorted.
Dont know how I did it.
Closed as many applications as pos. that were running in the background.
The next time I lookrd the files I was trying to delete had gone.

Pisces,

Can you advise me where I can download a plain chronograph similar to the chrono used by Friedl9te's video on OLC attach solution?

Thank.
