Keep that basket small. If your system has enough bandwidth you can
update
the weapon all the way to the target and at the terminal point it's within
the
CEP of the blast effect for the particular weapon you've selected.
Obviously the 2000lb JDAM requires less bandwidth for a given target.
Also obviously the performance of your SAR, GPS receiver, and datalink are
crucial.

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.

The JSF GPS receiver is significantly better than anything else on the market.
We'll be delivering the first EMD in September.

Google JPALS.
