[REL] 3D TDC and Radar Range Unit

IGD, I can't tell anything for certain from your plot data as you were obviously manouvering at the time, so I can't see definitely what was wrong. From the last three plots looks like your bearing might have been off.

Don't stop and start the stopwatch, keep it running as it's much more accurate that way. Assuming the target is on a straight course, after 30 minutes you can measure the distance travelled from the start plot and divide that by 100, which will give you a much more accurate speed.

Also, you're probably trying to do too much at once. You don't have to do everything at each step. You don't have to get a course and speed estimate each time (note that this is independant of starting and stopping the stopwatch and gets its time from the when you actually sent the data, nothing else). If you aren't getting an estimate every time, then you don't have to worry about sending it to the TDC. So, you just have to plot it.

As JCC says, take your range measurement and bearing then put an x on the back of the sub, if that's how you want to plot. From that point on, you don't have to plot it quickly and you can even pause the game. It also makes it much easier to plot if you stop completely, as you don't have to move all the tool around for each plot, but you may miss fast targets if you do that.
