No Sign of End to GPS Jam

GPS jamming signals that have been coming from the Kaesong region of North Korea since April 28th show no signs of ceasing; however, there has been no damage done to property or people to date.

According to a source cited by Yonhap News on the 13th, “GPS jamming signals have been continuously emerging from the Kaesong area of North Korea, including today. However, there have been no cases of damage to our side’s military or civilian equipment.”

The source explained, “Most key equipment such as the military’s fighter jets, transporters and guided munitions carry a U.S. military code (‘P code’) receiver so it cannot be interfered with by North Korea’s GPS jamming signal. Private aircraft and ships also carry INS (inertia navigation system) or some other navigation system, and therefore North Korea’s signals cannot become a disturbance.”

Since the 28th of last month, 609 domestic aircraft from 10 companies, 48 aircraft from 22 American, Japanese and Chinese companies and one U.S. military aircraft have reported being affected by the GPS jamming signal.

The South Korean government has reported the issue to the UN affiliated International Telecommunications Union (ITU), requesting a ruling on whether the jamming violates international rules. North Korea is a member of both the ITU and International Civil Aviation Organization (ICAO).
