N.Korea Developing High-Powered GPS Jammer

North Korea is reportedly developing a GPS jamming device capable of disrupting signals more than 100 km away. The North has several times disrupted signals in South Korea from Kaesong and Mt. Kumgang.

The information comes from a report the Defense Ministry submitted to the National Assembly's Defense Committee on Tuesday.

The North currently deploys vehicle-mounted jammers capable of disrupting signals within 50-100 km which it imported from Russia in the early 2000s. They are deployed near the Demilitarized Zone.

The report said electronic warfare regiments are deployed in the Pyongyang area and at each of frontline Army corps.

The North has about 20 kinds of communications and radar jamming devices that it imported from the former Soviet Union.

A ministry official said there is "no confirmed intelligence" that the North has so-called electromagnetic pulse bombs capable of paralyzing all electronic devices, a kind of Bigfoot of military intelligence the world over, but it is "likely" that the North is trying to develop them.

The jamming attacks earlier this year did have some effect on South Korean weapons and navigation systems using commercial GPS devices. But the military was able to carry on as normal by using alternative equipment like radar and inertial navigation systems, the ministry added.
