As usual, the FAA leads the way...others follow.
ALL US scheduled GPS outages (IE: scheduled jamming trials, specifically geographically denoted) are broadly publicised well in advance, via NOTAMS to pilots and notice to mariners.
Normally, these exercises take place well after 11pm, local time, to cause the least disruption to airbourne/marine GPS navigation users.
Well then....wonder when Europe will actually wake up?
Answers on a postcard....
NB.
The US taxpayers provided the GPS system for use, free of charge...so don't complain.
