South Korean flights suffer GPS jamming
More than 250 flights in and out of South Korea have experienced GPS signal jamming since the weekend, with North Korea high on the list of suspects, officials said yesterday.
Similar jamming in the past was traced to the reclusive North.
The secretive country last month also breached US Security Council resolutions with a failed long-range rocket launch and was blamed for cyber attacks on South Korean financial institutions last year.
None of the flights, including 11 operated by foreign airlines, was in danger, the Transport Ministry said, with automatic switching of navigation to alternative systems.
“As it happened at the time of (military) drills in 2010 and 2011, we suspect North Korea was engaged in jamming signals,” a government official said.
News reports have said that North Korea operates vehicle-mounted jamming devices that can disrupt signals up to 100km away. And it is believed to be developing systems with further reach.
