Hydrophone tracking

comet61 · 11-29-09, 05:30 PM

I have been studying Nefelodamon's Hydrophone movie on tracking an enemy target and using mathematical terms to get a position and course for attack interception. This is if you are not using Map markers. Very interesting movie. I have been writing down notes and trying to practice this in theory in game....with miserable results.

Is there by chance a PDF version? The reason I am asking is that watching the movie over and over and going back to certain sections many times has become redundant to the point I am definitely missing certain aspects. The 4th bearing line has been a pain in the a$$ for me.

I am not trying to critique the method of explanation of this procedure, however, the "quirkiness", "pauses" and having to use "pause/play/reverse, etc. dissolves the train of thought (this is why I was always a C student...at best

).

To me, this method of tracking is very exciting and granted, the margin of error regardless of how attentive one can be is a little bigger than I had hoped. Don't get me wrong-Nefelodamon did an outstanding job and I am grateful, however, I guess I am one of those souls that needs to read the "book".

it might be an idea to mail him direct - see what answer you get: i am in agreement with you, my ability to absorb anything mathamatical takes some doing - over and over again.

Have you tried doing it on paper as an example? With pencil, ruler, compas... and don't forget a rubber. (somehow that sounds funny

)

Draw a line making the path of the target.

Choose a point away from it where your uboat would be.

Plot 3 points on the target path to make the 3 bearings, and define the speed it has.

And then go from there, while ignoring the first line you made. Because that's the one you need to re-figure out. When you do it in the game the tension could be playing against you. Likely causing you to make mistakes. Paper is patient. And you can easily draw up different situations: heading sharp towards you, allready past and moving away, or halveway at closest range.

I think that's what you're looking for ( see the 2 Pdf sheets ) here :

No risk of STDs aboard a Uboat I would think being the manly warriors they are,although that depends upon the duration of the patrol and the severity of cabin fever

There's also the three bearing AoB finder wizz wheel thingymajig, which takes all the plotting out of it. Comes as standard with the Magui, but there's also a pdf to make your own somewhere.

A lot has changed with me concerning hydrophone tracking. Gettin to be old hat with it now. I haven't had the chance to try out Magui's AoB "whizz" wheel in-game yet.

On another note: Concerning the distance traveled before taking the 4th bearing line reading, if my bearing intervals are 10 minutes I will turn somewhat permindicular and stay submerged at flank speed. If the intervals are 15 minutes or more I will surface and go as fast as I can and submerge for the 4th bearling line. Usually if my readings are 10 minutes the target is somewhat close.

I have been playing this game for over 7 years and I just found out about this... I think I am in love with this game all over again... I found this right in time too since I started a new campaign with map updates off! I love you guys!

This is interesting, as I'd like to spend less face-time with the scope later on in the war.

I've been wondering just how effective this method is in-game. Seems like something fun to try, now that I've pretty much mastered the 3:15 method with periscope/charting. I always just used the phones for finding a new victim, or to confirm a torp hit when visual confirmation is not safe (and it's quite satisfying to hear the torp's humming slowly converge on the target's bearing).

I get a lot of personal use out of the hydrophone due to my sonar guy's hearing impairment. Using it to track things semi-accurately will likely make me forget about the SO's shortcomings and that bumps up the immersion factor for me. In simulators, nothing breaks the 4th wall like a good ol' bug does.

SO: No sonar contact, sir.
Me: Oh bull, lemme listen! ...
(merch screws audible even at Ahead 1/3)
Me: Alright Beethoven, clean out your locker, you're FIRED!
