DOD “Red Flag” exercise ushers in GPS jamming season across West
War games in the sky, at sea, on ground block GPS to add a dose of reality.https://arstechnica.com/information-technology/2018/02/dod-red-flag-exercise-ushers-in-gps-jamming-season-across-west/Quote
That's where the GPS jamming comes in. The US and allied military forces lean heavily on GPS navigation, especially in the air—even some weapons systems depend on GPS for guidance. But because of the relative low power of GPS signals from satellites—as we've pointed out on a number of occasions—GPS is particularly prone to jamming or spoofing.
North Korea has become particularly adept at using GPS jamming to disrupt life (and military operations) in South Korea—even affecting air traffic flying into Seoul on several occasions and causing South Korean fishing fleets to return to port out of fear of drifting into North Korean waters.
This reminds me of my childhood in the end of the Cold War Era. I know it doesn't make sense, but this gives me a warm feeling inside.
