It comes as tensions between the two countries soar, with the North flying thousands of trash balloons into the South in recent months.
South Korea has accused North Korea of disrupting GPS signals from border areas, affecting dozens of flights and ship operations.
North Korea’s GPS signal jamming took place on Friday and Saturday and was detected from around the cities of Kaesong and Haeju, officials said.
“We urge North Korea to stop GPS interference provocations immediately and strongly warn that it will be held fully accountable for any resulting consequences,” South Korea’s Joint Chiefs of Staff said.
South Korea’s military did not specify how Pyongyang was interfering with GPS signals or the extent of disruptions.
Last month, North Korea blew up sections of its unused road and rail routes linked with the South, days after the North claimed that the South flew drones and dropped leaflets over its capital Pyongyang.
South Korea’s Unification Ministry described the North’s explosion as a “regressive” measure that violated previous inter-Korean agreements.
North Korea has sent thousands of balloons carrying bags of rubbish like plastic and paper waste into South Korea since May.
Last month, a North Korean balloon filled with trash fell on the presidential compound in Seoul for the second time, raising concerns about the vulnerability of key South Korean sites.
North Korea said it was retaliation against South Korean activists launching anti-Pyongyang leaflets via their own balloons.
In January, Northern Korean leader Kim Jong Un called for the rewriting of his country’s constitution to eliminate the idea of a peaceful unification with the South and to designate its neighbor as an “invariable principal enemy.”
