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.

Further, GPS + data link + terminal seeker has worked well in the past -- in
some cases, such as SLAM, at greater than "expected levels" for the program.
SLAM-ER, advanced Tomahawk, JSOW P3I, and other programs have built on the
baselines set by SLAM and other similar programs.


Do you have a reading disability, Weiss, or are you actually as rude as you
come off?

No reading disability; nowhere near as rude as you.

OTOH, you just made a couple statements that are apparently without basis or
relevance:

The Navy has been using GPS and data link in landing systems for quite a
while, in addition to TACAN. I am not aware of any current "Navy plan to
replace TACAN with GPS/Data link."

What does LAAS have to do with weapon terminal guidance?

I simply asked for some amplification, which an engineer with your claimed
credentials should be willing and able to provide. Otherwise, if you can't
answer valid questions regarding the basis for your statements, we can all
assume you're just spewing your usual BS, and no basis exists outside your
imagination.
