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.

I see... In your fantasy world, TLAM and JSOW are "irrelevant" in the context
of GPS guided weapons with terminal seekers, and so is the funded research in
the JSOW Preplanned Product Improvement program...

What current weapon[s] use[s] "GPS with FOG" and "does all that already"?

BTW, what is your definition of FOG in context? The gnomes at China Lake
couldn't make FOG-S (Fiber Optic Guided Skipper) work well enough for
operational use after many years of pork-barrel supported work...
