It starts with a story about a 2007 Navy exercise in San Diego. Two ships
jammed radios to simulate communications troubles and wiped out a lot of
nearby communications too. This is the first time I've heard about that one.

If anybody finds a good writeup, please let me/us know.
Fun story...

Pseudolites: Low-altitude signal boost systems are an example of
one GPS anti-jamming capability that is largely classified, but
likely to have been employed recently in Iraq.
I can't figure out how that's going to work. I think I could make it work
for one target location, but not for an area.
The next paragraph mentioned phased array antennas to null out jamming.
