Although the US military has not found too many (if any) GPS inhibitors on the battlefield, there is a threat. The most obvious evidence comes from North Korea’s long-term production, sales and use of GPS locks. In 2012, North Korea attacked South Korea through massive GPS jamming activities. The riots began in early 2012 and lasted for more than two weeks. Less than a day later, it was confirmed that this signal came from North Korea, mainly the North Korean capital (Seoul). It has little effect in cities with internally interfering cities (ground interference signals blocked by buildings and hills), with only hundreds of aircraft landing or taking off from local airports, and more than 100 ships near the coast of the working bank. In all these cases, ships and aircraft have other navigation systems that will be turned on when GPS is unreliable. This is the way to design navigation systems, especially those that rely on external (satellite) signals.
This is the third time North Korea has used GPS to interfere with South Korea. For most of March 2011, North Korea directed gps jammer signals to Seoul. A separate jammer has been selected for mobile communication. GPS interference signals can be detected 100 kilometers south of the DMZ. North Korea directs GPS jamming signals to Seoul.

Russian President Syria has dispatched fighters, planes and bombers, but this is a spy weapon and may be the most powerful and dangerous. Although the surveillance team and the “cellular signal interceptor” apparently prevented the Islamic State’s combat communications, Russia appears to be targeting Western armed rebels to show the power of the Almighty. In recent weeks, the Russian IL-20 reconnaissance aircraft has sent equipment called “Old Fool” to its NATO. The radar is equipped with listening equipment, optical and infrared sensors. It also deployed an advanced Krasukha-4 electronic lock system to lock enemy radar and aircraft. Electronic warfare is one of Russia’s greatest strengths, even in the West. The deployment of blockers will directly affect NATO’s technology, cause pilot blindness, and give Russia a huge military advantage in the West. According to the Times, Turkish and Russian-made fighter jets deployed the Suha 4 interception system three days after the Russian and Syrian regimes opposed the use of midair.
