The Chosun Ilbo (English Edition): Daily News from Korea – N.Korea Tries to Jam S.Korean Air Traffic

North Korea has been trying to disrupt air and ground traffic in the South for the fifth day running, the government said Wednesday. Aircraft taking off or landing in the Seoul metropolitan area and ships traveling off the west coast have been affected by electronic jamming signals from the North since Saturday.

The Ministry of Land, Transport and Maritime Affairs said that the GPS of a total of 272 airplanes had been disrupted as of 3:10 p.m. on Wednesday. They were taking off or landing at Incheon and Gimpo airports and flying over Osan and Taean, chiefly in the central region.

That effort to build a ultra precise INS system I posted a couple days ago looks pretty smart, huh?

While the article notes that the airliners and ships have other nav systems available, the jamming is potentially quite hazardous.  If it’s noise jamming and the receivers just aren’t getting a signal, that’s one thing.

But if the Norks are “meaconing” (mimicking beacons) and giving subtle false information to GPS receivers (a far more difficult task, by the way) that would be much more dangerous. Crews would be far less likely to realize that GPS is unreliable, and could easily find themselves dangerously out of position.

  1. We were always taught in 98C (SIGINT Analyst) AIT that jamming signaled the start of armed conflict. Mind you that was the ragged end of the Cold War, and basically if the Sovs turned on their jammers that meant they were rolling through Fulda on their way to the Atlantic.
