TMA while moving problems

Hmm... I see that I sorta deleted the thread that talked about the "Unit Advance" tool when I moved all the files over to the downloads area.

Maybe I should write an addendum to the manual to document some of the newer gadgets that have been added since the initial release of version 1.0?

Now this is elegant! I used the advance tool before. But not for this reason, rather for tracking several radio contacts.

Thanks a lot!

This is just one approach that happened to come to mind, it's not like I have some hardfast rules that I follow...

There are lots of other things you can do or dream up to analyze the target motion and solve for the target position/vector data.

For instance, you could take the example above and add two or three more predictions for a new bearing at 1550. Then use the advance feature again and do another triangulation at 1550 for a second position fix. Then you'd have two real triangulated positions with time elapsed as a given.

A line between those two positions gives you true course. Distance between the points along with the elapsed time allows you to calculate the target true speed (TSD calcs in MoBo are simple). You can do all this from your stationary location once you have a TMA track that you can use to predict future target bearings.

Good questions and happy hunting.

I really wish you would implement the least squared TMA into your app if possible. Would help things a bit
