REFLECTOR: GPS outage, no big deal

Similar GPS jamming tests were conducted earlier this year by the 
military that affected southeastern states.  The center of jamming 
activity took place several hundred miles off shore, and signal outages 
were expected from North Carolina to Florida.  Aircraft flying at higher 
(above 10,000') altitude were more vulnerable to GPS interruption than 
those flying at lower altitude.  During the test period, I did not 
notice GPS service interruptions in the Sebastian area.
