The country's Transportation Ministry said the electronic jamming has affected hundreds of flights by South Korean and foreign airlines and well as a U.S. military plane and 176 South Korean ships, Yonhap News Agency reported.
North Korea has been disrupting South Korea's GPS signals since April 28.
In addition to asking North Korea to stop jamming, South Korea's communications watchdog said it would raise the issue with the International Telecommunication Union and the International Civil Aviation Organization.
Son Dong-hwan, deputy director of transportation, said no accidents have occurred because planes and ships are able to use an alternate navigation system that employs motion and rotation sensors.
