So far the GPS/Data link combination has performed at less than
expected
levels. I havn't seen anything good about the Navy plan to replace
TACAN
with GPS/Data link and FAA just killed the LAAS landing system.

How is a proposed GPS/Data link landing system related to the current
JDAM
or its proposed seeker?

As the rest of the thread up to this point indicates, there is a desire
to
redirect a GPS guided munition post launch. The means to reprogram the
munition would require some data link.

Actually, data link is NOT a hard requirement. There have been several
initiatives in work for many years on autonomous terminal seekers -- TLAM
is one
significant example, though it may not have used GPS. I worked with some
relevant JSOW (then AIWS) P3I proposals at TI and a couple other places
back in
'90 and '91.

Irrelevent.

GPS with FOG does all that already.
