Ministry of Science and ICT Conducts Joint Civil-Military-Government Training to Prepare for GPS Signal Jamming

The Ministry of Science and ICT announced on the 22nd that it will conduct an on-site simulation exercise as part of the 2023 Eulji Exercise to prepare for response readiness against Global Positioning System (GPS) signal jamming.

GPS signal jamming refers to the act of transmitting interfering signals at a higher power than the GPS signals within the GPS frequency band, thereby disrupting the normal use of GPS signal-based services. This exercise is a joint training led by the Ministry of Science and ICT, the lead agency, with participation from related organizations including the Ministry of National Defense, Ministry of Land, Infrastructure and Transport, Ministry of Oceans and Fisheries, and mobile carriers, aimed at strengthening organic cooperation and response posture among government ministries against GPS signal jamming attacks and enhancing crisis management capabilities.

After receiving reports of GPS reception disruptions at aircraft, ships, and mobile communication base stations from the Ministry of Land, Infrastructure and Transport, Ministry of Oceans and Fisheries, and mobile carriers, the Ministry of Science and ICT promptly issued a GPS signal jamming crisis management alert at the 'Caution' level and took initial measures by notifying related agencies. To detect and eliminate the jamming source, a jamming removal team was dispatched to the site in cooperation with the military.

Related agencies and companies responsible for the aviation, maritime, and mobile communication sectors implemented their own safety measures to prevent civilian GPS jamming damage. The Ministry of Land, Infrastructure and Transport issued aviation security and hazard information to share with aviation personnel, and the Ministry of Oceans and Fisheries strengthened safety operation guidance for fishing vessels. Mobile carriers inspected the proper functioning of GPS jamming signal shielding facilities at base stations and anti-jamming antennas, and took measures such as temporarily relocating antennas where disruptions occurred.

Based on the results of this exercise, the Ministry of Science and ICT plans to identify areas for improvement and incorporate them into the relevant 'Crisis Management Standard Manual' and the 'Operational Manuals' of related ministries and companies.

Meanwhile, Park Yoon-gyu, the 2nd Vice Minister of the Ministry of Science and ICT, visited the Central Radio Management Office’s Radio Comprehensive Control Center on the day of the exercise to inspect the GPS monitoring and response system and encourage the participating staff. Vice Minister Park stated, “Since GPS is used in various fields such as aviation, shipping, and communications, large-scale GPS signal jamming is expected to cause significant damage. We will actively respond to minimize damage through organic cooperation among related ministries.”
