GPS signal alterations NOTAM.

Got this NOTAM right after flying yesterday. Interesting they are altering (??) the GPS as low as 50 feet AGL out 246NM radius on some dates over a four week span.

Fwiw, I see we also heard on news we moved to DEFCON 3 from 5 so that might be some of this.

More on that here: The DEFCON Warning System

That GPS testing has been going on for awhile now and covers a fairly small area. Doubt that it has anything to do with the DEFCON.

DOD and FAA have been doing this for years when they test the new toys. The DEFCON conspiracy site is the last place to get info from.
