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.

Fibre Optic Gyro.

GPS with a gyro of any kind does not make for post-launch reprogramming
or
retargeting of the weapon.

AMSTE (Affordable Moving Surface Target Engagement) uses a post-release
data
link to compensate for the long time of flight of the ballistic weapon
used
(JDAM).

We already discussed that and Weiss just wanted to argue.
