South Korea
Risk Level: Three - Caution
[ about risk levels ]
In 2024, South Korea started warning of GPS interference in the north of the country, likely originating from North Korea, advising pilots to watch out for ops to the Seoul airports of RKSS and RKSI. It’s especially important to watch out for GPS spoofing here - it’s right next to the border with North Korea and a bunch of prohibited areas which carry chart warnings that say in very clear language that you might get shot at if you inadvertently enter.
South Korea previously had warnings in place due to the risk posed by unannounced North Korea missile launches and regional volatility. A US Notam on GPS interference expired on May 27, 2019.
Major events:
May 2024: Member report of GPS spoofing into RKSS/Seoul on approach to RWY 32R. They disabled hybrid and deselected GPS after seeing the risk reported on ATIS.
