GNSS outage due to DOD testing
Take a look at the map...Comments Mr bomber? 215nm radius @ 4000ft. Truelly global in area!
Pilots are highly recommended to report anomalies during testing to the appropriate ARTCC to assist in the determination of the extent of GPS degradation during tests.
Interesting!
If the DOD is interested in feedback....suggests the DOD doesn't have to turn off the entire network to have the desired effect in a war theatre sized area of the planet.
