This is North Korea since 2010, the fourth round of the GPS interference. Previous attacks affected about 1,000 civilian aircraft and Korean military unmanned aircraft. An attack in 2012 reported a GPS-based car navigation system that affected Seoul’s capital.
South Korean officials emphasized that the attack had not caused a serious GPS disturbance since the aircraft could also use the old inertial navigation system (INS). INS does not depend on external signals and is anti-card.
North Korea has developed its GPS jamming capability to respond to GPS-guided weapons that can be used by South Korea and US armed forces in the war. The country has a global global positioning system (OTC) near the Pyongyang capital and close to the camps near the demilitarized zone. Jamming was pursued in 2012 to open the city, on the border.
North Korea allegedly bought thirty to sixty miles of truck-type GPS Jammer from Russia, which was reportedly working at a longer distance jammers in 2011. Sixty miles far more than Seoul has half the population of the Seoul metropolitan area.
In response to possible GPS interference, the countries have different responses.
The British General Lighthouse (GLA) follows seven new electronic Roland stations. GLA engineer Martin Bransby said that this would replace the visual navigation as a great backup of GPS. It will work in mid-2014 at a price of less than £ 700,000; The receiver costs £ 2,000 per ship. By 2019 coverage should reach all major British ports.
The US military research agency DARPA has an experimental “single-chip timing and inertial measurement unit” (TIMU). After completion, according to the project owner Andrei Shkel, it will use tiny gyroscopes and accelerometers to track its position without satellites or towers. The New Mexico-based US White Sands rocket system installs a “non-GPS-based positioning system” that uses ground antennas to provide more than 2,500 square-centimeter-level positioning. In May, the Canadian government said it would have an impact on the anti-jamming armament of military aircraft.
A new version of the bunker bomb of the US Air Force, which is partly destined to destroy the nuclear power plants of Iran, includes techniques to prevent defenders from blocking their satellite navigation systems. MBDA is a European missile company that carries out similar work.
But for many users, GPS and other space-based navigation systems – including the Russian GLONASS, some of China’s complete Beidou and unfinished EU projects – are still indispensable and omnipresent. They are also very fragile. For those whose lives or lives depend on where they are, the more flexible alternatives can not be fast enough.
