North Korean, Chinese Jammers

摘要

A South Korean media source, the Chosun flbo, reported in late May that North Korea has been attempting to export a device capable of jamming GPS signals, copied from a Russian unit, to Middle East countries including Iran and Syria. When the Iraq War began in 2003, the Iraqi Army reportedly used a Russian-made GPS jamming system to attempt to disrupt the U.S. military's guided weapons systems such as the Joint Direct Attack Munition (JDAM), a GPS-based bomb-guidance system, and long-range air-to-ground GPS-guidedTomahawk cruise missiles.
