it's harder to do well than some would have you believe, but it's still
a genuine concern with fewer easy answers you suggest.

If there's a cheap, quick, easy and reliable magic bullet to make GPS
unjammable, then hasten down to your patent office at once.

I might mention that as of the first of '03 I'm pretty much off of
AESA radars and have been working on airborne GPS receivers.
It's my first experience with them and it's illuminating,
but I've learned enough to:
a] be dangerous, and
b] know enough of the performance limits to not be pessimistic.

Fair enough - in the same timescale I've been doing work for NAVWAR and
the RN on the effects of GPS denial, how it might happen, how to work
around it, and how to prevent it
