Some 1,137 aircraft and 265 ships in South Korea were affected over the past three years by North Korean GPS jamming signals. The North launched three GPS jamming attacks since 2010, according to data the Central Radio Management Office submitted to Saenuri Party lawmaker Lee Jae-young.
The first jamming attack, which lasted four days from Aug. 23, 2010, originated in Kaesong, disrupting the GPS signals of 15 aircraft and one Navy ship. The second was severer. It lasted 11 days from March 4 last year, came from Kaesong and Mt. Kumgang, and disrupted the GPS of 106 aircraft and 10 ships.
Third attack was even worse, lasting 16 days from April 28 this year and affecting 1,016 aircraft and 254 ships. The signal again came from Kaesong.
