North Korea has staged a Global Positioning System (GPS) jamming attack, Seoul\u2019s military has said, an ongoing disruption operation that has affected several ships and dozens of civilian aircraft in South Korea. South Korea\u2019s Joint Chiefs of Staff (JCS) on Saturday warned ships and aircraft operating in the West Sea area, also known as the Yellow Sea, to be cautious of North Korea\u2019s GPS signal jamming. \u201cNorth Korea conducted GPS jamming provocations in Haeju and Kaesong yesterday and today [November 8-9],\u201d the JCS said in a statement, adding that several vessels and dozens of civilian aircraft were experiencing \u201csome operational disruptions\u201d as a result. GPS relies on a network of satellites and receivers that allows for global positioning and navigation. The JCS also called on North Korea to immediately halt the interference and warned it would be held accountable for its actions. Between May 29 and June 2, an estimated 500 planes and hundreds of ships experienced GPS problems due to North Korean interference, South Korea\u2019s government said at the time. Seoul complained to the United Nations aviation body, the International Civil Aviation Organization (ICAO), which warned North Korea to stop the jamming. South Korea\u2019s Yonhap news agency said on Saturday that the latest GPS \u201cjamming attack\u201d involved a weaker interference signal compared with the widespread interference North Korea perpetrated in May and June. South Korean military operations and equipment have not been affected, Yonhap said, citing the JCS. Tension between the two Koreas has escalated in recent months amid missile tests by Pyongyang, North Korea\u2019s destruction of transport infrastructure connecting the North with the South, the recent dumping of rubbish over South Korea from balloons launched in the North, and the reported deployment of North Korean troops to fight for Russia in Ukraine. Aviation experts said North Korea\u2019s rubbish balloon campaign, numerous ballistic missile launches and the emergence of GPS \u201cspoofing\u201d \u2013 where a signal is transmitted to override a legitimate GPS satellite signal \u2013 have increased risks in South Korean airspace, complicating airline operations as tensions rise between the rival nations. Yang Moo-jin, president of the University of North Korean Studies in Seoul, told the AFP news agency that the reason for the jamming operation needs to be analysed. \u201cIt remains unclear whether there is an intention to divert the world\u2019s attention from troop deployments, instil psychological insecurity among residents in the South, or respond to Friday\u2019s drills,\u201d Yang said, referring to South Korea\u2019s test firing of a missile. \u201cHowever, GPS jamming attacks pose a real risk of serious incidents, including potential aircraft accidents in the worst-case scenario,\u201d he said. South Korea fired a Hyunmoo surface-to-surface short-range missile into the West Sea on Friday, which the military said was to show Seoul\u2019s \u201cstrong resolve to firmly respond\u201d to any North Korean threats. Hyunmoo missiles are key to the country\u2019s so-called \u2018Kill Chain\u2019 preemptive strike capacity, which would allow Seoul to launch an attack if there are signs of an imminent North Korean attack.<\/p>\n","protected":false},"excerpt":{"rendered":"
