Can anyone help me out here.

I am searching for software or algorithm that can be use to convert from LAT/LONG to Loran. There is plenty of information to go the other way.

Thanks.

Carl

Why? I can’t imagine anyone ever needing such an algorithm

and how the hell could you even do that considering each and every chain is different with multiple pairs to get TD’s for?

just nonsense

But not LL to TD… I can imagine if you dig up a old log or something with a string of TD’s that needed to be converted to LL but the other way around? I wonder if it’s maybe a lawsuit or something where navigational accuracy is in question… Then like c.captain says, which chain? X,Y,Z? Differential?
