Springhill Group: DPRK jams GPS of ROK Airlines l Blogger - Zimbio

GPS jamming signals coming from North Korea has forced South Korea to order its military and civilian air transports to switch on alternative navigational devices to avoid disruption.

A statement from the ministry has confirmed that they were able to warn airlines and pilots of the 241 affected South Korean flights along with the 11 foreign airlines like Thai Airways, AirPhil, FedEx, Japan Airlines and Cathay Pacific Airways. But even as the GPS jamming signals continued, South Korea sees no serious threat to navigational safety.

Korea Communications Commission confirmed that the GPS jamming signals have been coming from a city on North Korea side of the border. “We’ve traced the jamming signals to the direction of Kaesong,” a commission deputy director told Springhill Group.

According to the transport agency, planes that suffered from GPS signal jamming were instructed to use the alternative navigation systems and were not delayed in their schedules. The signal jamming appears to be focused on air traffic at Gimpo and Incheon airports, both of which are around 30 miles from the border.

Despite the GPS disruption, Springhill Group reports that there was no serious threat to flight safety as airplanes are capable of using other navigation devices like inertial navigation system and very-high-frequency omni-directional range (VOR). Meanwhile, military communications and transportation were not greatly affected as they do not primarily depend on the GPS system. » Springhill Group: DPRK jams GPS of ROK Airlines l Blogger - Zimbio
