[Iraq] purchased a number of GPS jammers from Aviaconversiya Ltd., a Russian company that has been hawking GPS jammers at military hardware shows since 1999 ...
.. Iraqi military used at least six of these high-powered GPS jammers, which cost $40,000 or more each, during the war. All six were quickly eliminated by U.S. forces over the course of two nights.
...high-powered GPS jammers can easily be traced back to their origin, effectively painting themselves with a bull's-eye. "In fact, we destroyed a GPS jammer with a GPS weapon," U.S. Major General Victor Renuart told reporters at a briefing in Qatar that described the attacks against GPS jammers...
...the US military is lobbying for the launch of 20 new GPS satellites starting next year. These new satellites would transmit a GPS signal eight times stronger than the current signal ... any potential jammers would have to increase in size and complexity.
