Just one question...when you are nearing the end of the solution plotting, you send the range/bearing information to the TDC 5 or 6 times. Why? Does the TDC automatically average the range estimates or were you looking for a good result and repeating the process until you found it? |
No unfortuanly it does not.
Ive just done it to hit an average. As i said there is a small sonar error. So when you ping a target and you get numbers varying between 2500 and 2000 you should ping it until you are at about 2250 then you have the everage and rather close to correct solution and you can stop.
Basicly - the shorter the time between your last data update and your attack, the less critical will solution errors take effect. Example. You have a solution that is wrong in speed by 1 knot. Now lets say you dont update bearing for about 3 minutes. Your solution will be displaced from real target alot more then if you have updated bearing just before you release the fishes. So the most important thing about it is the correct bearing when you fire. When you update the bearing just before you shoot, they will more likely hit even if the solution is flawed by little.
