Military GPS jammers that interfere with navigation

　　When the Iraq War broke out in 2003, the Iraqi military caused a sensation when it used a Russian-made GPS signal jamming system to destroy the US-guided weapons system. South Korean military authorities are doing their best to develop countermeasures, fearing that the equipment could cause similar damage to South Korea and its allies in the event of war.

　　Long-range air-to-surface cruise missiles, including the Tomahawk cruise missile, are also GPS-guided. The advantage of GPS-based weapon systems is their ability to hit targets accurately in severe weather and difficult terrain. The downside to them is that they get stuck easily even with weak signals.

　　China appears to be moving forward with plans to use electronic attacks designed to destroy or control U.S. drones. The country has expressed a willingness to use GPS jammers to prevent U.S. aircraft from conducting surveillance missions in the Spratly Islands, and there have been reports that China has attempted to jam U.S. military drones at least once in recent years.

　　GPS jammers currently on the market can be purchased for less than $200, but the military appears to be testing more powerful systems that can jam the GPS of unmanned and manned aircraft. Creates a portable GPS signal jammer that could severely damage U.S. satellite guidance systems in Iraq.

　　However, if the tag GPS does not work, or the GPS is used incorrectly, for example for illegal tracking. It is known that it is very dangerous to put all your eggs in one basket, so there are alternatives to GPS navigators. They are GLONASS, Cell Tower Triangulation, and Wi-Fi Navigation. GLONASS is very clear to the public, as Russia's analog GPS, cell tower triangulation, and Wi-Fi navigation may require some explanation.

　　Sea, air, and land navigation all rely heavily on GPS. Many weapon systems, such as cruise missiles and GPS-guided bombs, also rely, at least in part, on technology to reliably and accurately hit their intended target. When GPS signals are unavailable or unreliable, combat troops are severely paralyzed. GPS satellites can be attacked by both dynamic and non-dynamic (jamming, hacking, etc.) methods.
