North Korea has launched a GPS jamming campaign affecting multiple vessels and dozens of civil aircraft in South Korea, according to the South Korean military. This escalation comes amid rising tensions following North Korea’s recent missile tests and accusations of deploying troops to assist Russia in its conflict with Ukraine. South Korea has warned its civilian fleet operating over the Yellow Sea to exercise caution and urged North Korea to cease its disruptions, emphasizing that they will be held responsible for any ensuing problems. GPS jamming poses operational challenges by emitting interference that renders navigation systems unusable.
