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.

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.
