The four bearings method

Kuikueg · 06-05-10, 01:43 PM

I have been searching the web for info on this and what I found was not satisfactory. So I have done my own thinking and put together a document with my results. I hope you find it useful. Here's the link:

http://www.filefront.com/17135612/fo...ngs_method.pdf

If I have time and can figure out how to record in Windows (Linux man, me) I'll try and demostrate my method.

Edit: corrected link to filefront new upload of the document. I don't know how long will these people host the file. It seems that they dump it after sometime...

Welcome aboard!

To record under Windows, try FRAPS.

You didn't specify what you were trying, but based on the bearings hint, I assume you mean getting the enemy speed.

Did you search the subsim forums? There is already a lot of information on this and other aspects of manual tracking and targeting.

Enemy speed, course and position is what you can find with four bearings.

Yes I've tried these forums for info. If you read my document, you will find that some of what it says contradicts what others have said before about this matter. I'm a mathematician and I had to check, you know.

FANTASTIC solution Kuikueg !

you solved a very difficult geometrical problem with a very 'classed' solution !

The 'beauty' of Euclid Geometry is always ,by far, much levels beyond other math's techniques.

Congratulations sir !

Excellent read Kuikueg. Once I get my Mod up and running I should have some time to try this out.

Works here now. Filefront has issues from time to time, just try to download again in 10 min or so.

1) There is alot of material out there. For example: Link: http://www.subsim.com/radioroom/showthread.php?t=161283

2) Regardless of existing material, "essays" as yours are always welcome!

3) The more discussions, tools, texts, methods we have at our disposal the better!

Ah! Also check the MOBO subforum and related posts here in subsim!
Alot of good work there!

Yes there are a few things out there that I had not found, specially that maneuvering manual from 1941 which is of the utmost interest for me.

Hey, great document. That red line in the general (moving) case is an interesting concept. Have to try it out on my way back to port.

p.s. On page 6 you mix up Sq and Sp.

All you high school students take note: it pays to be attentive in high school geometry class.

Oops! You're right. Inconsistent notation. Thanks, I'll try and fix it.

I guess you should pay attention in English also.
