Did that times problem solved and i missed it?

If you are not talking for celestial navigation then how are you determining your own position on map ? is there a procedure for determining your position with great accuracy ? i am suspecting that without your boat showing on map ,you will always have inaccuracies which are more responsible for the final outputs



hello B_K,

i didn't said that is a 'historical' method.i made the video with sh3 thats why you see it here.
I explained at the description of the video why i used the hydrophone lines.Of course,there were not back then hydrophones with super accuracy ,not even today. Even today , bearings from whatever passive device (even periscope's bearings) are not super accurate.All of them have a little 'cone' and crew is following extra procedures for minimazing the errors at outputs,procedures that demands special equipment.
The purpose of the video is to show the principles of Spiess TMA

Most importantly - which GUI are you using? Is it your new one that is still in development?

Yes is prety. Purse add hitman disc, which is mod useful for calculation that old attack disc reverse. I'm taking about the disc with double external ring.
