I don't quite understand. The Position Keeper is only as accurate as the information fed into it, so it should go to pieces if the target changes course while nobody's looking. How does that make it know where it is (the GIGO principle comes to mind; even a modern computer doesn't have that ability unless data is updated constantly from a GPS system).

Yes, if the target changed speed or course, the position keeper will not be able to provide a "valid solution".

With TDC w/ position keeper the following will be possible.
T = Enter target range, target speed, target AoB , target bearing into TD
T+60s = turn parrallel course to target course.
T+70s = Make quick observation. (observe bearing, range and compare values given with TDC. (you would at minimum want a matched bearing)
T+75s = Fire all 10 tubes. at target.

With TDC w/o PK only the following can be done.
T = Enter target range, target speed, target AoB, target bearing.
T + 1s = Fire torpedoes.

The big difference is that with TDC w/PK, is that the sub captian will have to possiblity to "checking the solution" and to see how accurate it really is before shooting.
