The target estimated loacation is marked in your navmap and it is on a NW course running faster then 10 knots.<R>

A very simple scenario for the absolute beginner that want to learn manual sonar and TMA stations. The sole purpose of this mission is to practice with sonar and TMA.

The tasking of this mission contains some indication on how it should be performed and evaluated.

 

The target estimated loacation is marked in your navmap and it is on a NW course running faster then 10 knots.

:::EXECUTION:::
A) when you first make contact with the target mark your position and time on the navmap.

B) choose a TMA tactic to practice and start tracking the target:

1. Point-Lead-Point<R>
2. Point-Lead-Lag<R>
3. Point-Lag-Point<R>
4. Point-Lag-Lead<R>

Each tactic is made of three legs if the next leg is a LEAD you should steer your boat of about +/-70° relative to POINT bearing, if it is a LAG one you
should steer the boat of about +/-50°relative to POINT. Be careful, do not put the target in your baffles.

C) try to ID the target in narrowband, and as soon as you have an high confidence about it, mark your position on the navmap and write the time.

D) when you are confident with your solution: PAUSE the game, mark it on your navmap writing current time, turn Truth on and compare it with the real target location and heading, and take note of the errors.<R>

:::EVALUATION:::<R>
Compare your errors, with the tables below.[BE=Bearing Error, CE=Course Error, SE=Speed Error, RE=Range Error]

OPTIMAL SOLUTION
BE < 1°
CE < 1°
SE = 0 kt
RE < 0.5 nmi (1012 yd)

ACCEPTABLE SOLUTION
BE < 2°
CE < 5°
SE < 1 kt
RE < 1 nmi

Also, take into account the time elapsed for getting both target solution and identification.


This scenario could be played with different sub platforms.

EDIT:
I initially made this scenario just for myself, after reading this paper:
http://calhoun.nps.edu/bitstream/han...pdf?sequence=1
I wanted to sistematically try out the "matematically ideal" TMA tactics in DW, I thought it was funny to try out and potentially could give me more insight on many things.
