[I'm goin' down]

I reviewed the tutorial for the Hydrophone Tracker stand alone program. It is "Calculating a ship’s course, speed, and position using data from the hydrophone,Tutorial" authored by jerm138. One does not need to use the stand alone program to calculate the target's course or its position on this course, as the tutorial explains how to triangulate the target's course and its position on the course using the Attack Map tools. He explains the concepts simply and concisely, and then shows how to accomplish the task with screen shots.

Once the target's course and its position on the course is determined, using the Easy Aob mod, you can input the target's course and manually input range from the Nav Map on the stadimeter at turn on the PK. Since the manuial input of range is an estimate, alternatively I think you can turn on the PK, go to the hydrophone station and send hydrophone readings to the TDC to confirm range. You can then use the Stadimeter to fix range and aspect ratio. This sounds like it will work wih map contacts off, but if any of you see problems, feel free to point them out. Jerm138' tutorial is not difficult to understand, and he does a great job explaining the concepts. In fact, it has elements of a masterpiece.
