GPS Jam.

This is coolbert:

Then and now. "In time of peace prepare for war!"

1. "Norway: GPS jamming during NATO drills in 2018 a big concern"

"COPENHAGEN, Denmark (AP) — The Norwegian Intelligence Service says GPS [Global Positioning System] signal disruption as seen during major NATO drills in Norway last year 'is of particular concern' for the military and 'is also a threat to civil aviation in peacetime.'”

A FOREIGN POWER [UNNAMED] EVIDENTLY HOSTILE TO THE NATO ALLIANCE HAVING SUCCESSFULLY [?] INTERFERED WITH  NAVIGATIONAL SIGNALS [GPS] DURING RECENT WAR GAMES VICINITY NORWAY!!

Furthermore thanks to the Aviationist, currently, right now, as we speak:

2. "Basically, Carrier Strike Group 4 [CSG-4] Is Jamming GPS Across U.S. Southeast Coast"

 "the U.S. Navy’s CSG-4, that 'mentors, trains and assesses Atlantic Fleet combat forces to forward deploy in support and defense of national interests', is currently [Feb. 6 – 10] conducting GPS Interference testing in the East Coast area . . .  GPS could be degraded from Caribbean and Florida north to Pennsylvania west to the eastern Louisiana, while the tests are conducted Feb. 6 – 10, at different hours."

Goals of such deliberate jamming and interference: A. Determine to what degree YOU are able to deny the adversary navigational signals of the GPS variety and do so on-call. B. Determine to what degree YOUR own personnel are able to function without having to resort to navigational signals of the GPS variety.

Does the navy and air force still teach celestial and astral navigation? Does the army still teach map reading and land navigation in the ancient and venerable manner? Compass, pacing, orienteering.
