I don't claim to be an expert, but when GPS made way for Differential GPS
wasn't it the LORAN system they used to add that capability?

It's been a long time since I was concerned about such things so my memory
is a little fuzzy, but I thought they placed high end GPS receivers at the
LORAN stations. Since the receivers are fixed and at precisely known
locations the difference between GPS located and actual location can be
calculated and used as a local correction value. I _thought_ this signal was
added to the LORAN broadcast signal. If all this is as I remember it,
wouldn't that suggest the LORAN system will be with us for many years to
come?

Wouldn't be the first time I was wrong though, heck, not even the first time
today. :-)
