Finding Contact Course and Speed with Passive Sonar
 

Hi all, I remember a about a year ago having some handy PDF detailing how to find a sonar contact's course and speed using only bearings. Looking through the forums now though, I can't find it. Driving me insane! Anyone have a copy/know what I'm talking about?

THEBERBSTER has that documented in the SH5 folder: Using The 4 Bearing True Method By Trevally

There is another thread of that some where, and I thought there was a video linked in Rockin Robbins thread Sub Skipper's Bag of Tricks, but I cannot find those...

Youtube matey, youtube.

There's the hits from Moonlight! The WernerSobe version is what I was thinking of for the vid! I think somewhere in the SH3 threads is a tutorial with pictures... I might have it on my hard drive somewhere buried in these hundreds of gigabytes of hard drives... yeesh! :salute:

:subsim:Found everything I need.
