Default GPS interference and contests

It seems as if GPS interference testing is becoming more widespread.

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?


This schedule covers days when someone thinks they might want to run a
test, in practice, there are somewhat fewer live tests. The contest
staffs here check NOTAMs daily, if there is notice of a test, they'd
task away from the affected area, or cancel the day if not possible.

I have an IGC file (which I'd be hard pressed to find) from a day when
there was a NOTAMed test at China Lake (roughly 200 miles to the south
of my location), not much to see, except for a few gaps of a couple of
minutes each...
