Over 2,000 aircraft suffered GPS jamming
A South Korean lawmaker has claimed that 2,143 aircraft have suffered jamming from the North since 2010.
Citing a report from the Ministry of Land, Infrastructure and Transport, Jeong Yong-ki of the ruling Saenuri Party explained on 11 October that GPS jamming under Pyongyang's direction had taken place on 4 occasions, affecting:
- 14 aircraft in August 2010
- 106 aircraft in March 2011
- 1,016 aircraft in April 2012
- 1,007 aircraft in March 2016
The number of aircraft affected per day of jamming has also increased:
- 4.6 in 2010
- 63.5 in 2012
- 167.8 in 2016
The ministry said jamming signals originated from 5 North Korean regions - Haeju, Yonan, Pyonggang, Kumgang and Kaesong - between 31 March and 6 April this year, compared with just one - Kaesong - in 2010. It added 'The jamming signals were weak in the past, but recently they have become stronger'.
South Korea has been beefing up its capability to counter North Korea's jamming in recent years, with reports of conducting drills regularly, actively developing detection technology and preparing to install eLoran transmitters.
