In the first place, the motivator is finding a backup for GPS that is
sufficiently removed in frequency and technology that both cannot be jammed;
users world-wide are demanding this. Second, your "small market" argument
fails when you consider the number of industries that are dependent on
timing...the telecommunications industry is one major market. Just read the
references I have given (and I have many more) to get the big picture. Or
Google "loran + gps.

Don't limit your thinking to aviation and maritime uses.

Roger, you and C. J. Campbell are referring to what is now known as
legacy
loran.

Still does not address the issue of cost, though. Why develop an expensive
system the cost of which will be spread across a tiny user base when GPS
works just fine?
