Pyongyang denies GPS jamming
May 19th
North Korea denied on Friday that it played any part in a two and a half week long jamming of Global Positioning System (GPS) signals in the border area between North and South Korea.
The denial was carried in several state media outlets and said allegations that the DPRK was behind the jamming were part of “a new farce and smear campaign.”
The jamming took place between April 28 and May 14 and resulted in several hundred civilian aircraft and ships experiencing disruption to their navigation systems, according to reports. It made GPS signals unavailable or unreliable but didn’t result in any serious accidents. South Korean More >
GPS jamming ends, says report
May 16th
The apparent intentional jamming of Global Positioning System (GPS) signals that has disrupted service near the Korean border has stopped, Yonhap news reported on Tuesday.
The jamming has caused inconvenience to hundreds of commercial aviation flights and international shipping since it began on April 28. The source of the interference isn’t known but South Korean media have quoted government sources as saying it’s been coming from the North Korean city of Kaesong.
The signals ended on Monday, said Yonhap.
The end of the interference came on the same day that South Korean President Lee Myung Bak and Chinese premier Hu Jintao met in More >
DPRK jamming GPS signals, says Seoul
May 3rd
Interference is causing problems with Global Positioning System (GPS) signals around Seoul and the South Korean government says North Korea is to blame.
GPS signals became unreliable on April 30 and more than 250 commercial aircraft has to rely on other navigation methods, according to several local media reports.
A spokesman for the Korea Communications Commission told The New York Times. “We believe that the jamming signals originated in North Korea,” but a different spokesman told AFP that North Korea had been confirmed as the source.
“We’ve confirmed the GPS jamming signals have been stemming from the North,” AFP quoted KCC deputy director Lee Kyung-Woo, More >
Report: Stronger GPS jammer developed
Sep 9th
North Korea has developed a powerful jammer that can disrupt GPS (Global Positioning System) satellite signals over a range of “more than 100 kilometers,” according to a South Korean government report, Yonhap News said Tuesday.
News of the jamming equipment was included in a report submitted to South Korea’s parliamentary committee on defense this week, the news agency said.
The South Korean capital lies about 50 kilometers from the border region so a jammer with such range could disrupt or wipe out GPS signals in Seoul and the surrounding area. The city and region up to the border is littered with military More >
Report: DPRK again jams GPS signals
Mar 7th
North Korea attempted to jam GPS (global positioning system) satellite navigation signals in South Korea on Friday afternoon, according to a Yonhap News report that cited an unnamed South Korean defense official.
Jamming is the act of broadcasting a signal on the same channel as the intended target service so as to confuse or interfere with reception.
The report said GPS disruption was recorded in some devices in the capital Seoul and two cities closer to the border, Incheon and Paju.
One report said the disruption caused some cell phones to show the wrong time. No more details were provided, but that would More >
North Korea Appears Capable of Jamming GPS Receivers
Oct 15th
The Voice of America has an interesting story on the jamming of GPS signals along the border region. The jamming signals are apparently from North Korea and rendered GPS systems in the region unusable.
This week, the South Korea Communications Commission informed lawmakers that between August 23 and 25, signals emanating from near the North Korean city of Kaesong interfered with South Korean GPS military and civilian receivers on land and at sea.
In theory, the jamming of GPS isn’t difficult. All that is required is a signal powerful enough to disrupt or override the relatively weak signals being received from space. The More >
