China appears to be planning to use electronic attacks designed to disrupt or control U.S. drones. There have been reports in recent years that the Chinese have tried to interfere with U.S. military drones at least once, and are ready to use gps signal blockers to prevent U.S. military aircraft from conducting surveillance missions in the Spratly Islands.
Since both the FAA and the Navy are turning a blind eye to upcoming experiments, it is difficult to determine which test will be performed. Currently, gps jammer under $ 200 are available on the market, but the military seems to be testing more powerful systems that can disrupt the signal stoppers of GPS satellite systems for drones and manned aircraft.
GPS jammers are designed to protect areas and assets from threats from satellite navigation, such as GPS guided missiles. High-powered drone jammers with interception of GPS signals can also be used for low-flying drones. GPS interference can be effectively used in combat situations to eliminate satellite-guided weapon systems, missiles, and ground / air threats. It is designed to operate on all available satellite navigation systems, now or in the near future. Some high-powered drone interception systems provide an intercept distance of up to 5 kilometers, and the specific interference range is affected by local signal strength.
