It seems as if GPS interference testing is becoming more widespread.
See: http://www.navcen.uscg.gov/gps/gpsno...terference.pdf

I wonder if anyone has thought of what might happen if one of these 'tests'
happened near the time an place of a sechduled contest. Basically, you
would lose all GPS systems including loggers. Back to photos? Anyone
thinking about contingencies?
