A GPS wifi jammer is easy to build. GPS signals are relatively weak and centered around frequencies of 1.0, 1.2, and 1.5 GHz, which are in the microwave spectrum. Simple emission of microwave energy in the vicinity of a receiver will mask out the weak signals transmitted by satellites (which are ~20k kilometers away) and render the GPS unit ineffective.
Drone Gun system can detect, track, identify and defeat a drone in approximately 3 seconds up to a range of 15 km or 9 miles. It can even detect multi-band drones using RF detection in real-time before using a radio frequency (RF) jammer to defeat the drone. A fully integrated, long range auto target tracking camera backs up the RF detection and is used to verify the drone type and payload.
Military wants to prevent the FAA from decommissioning radio NavAids and secondary radar. The FAA had counted on $100 billion from the decommissioning after the introduction of ADS-B. signal jammer GPS signals forces aircraft to rely on the old systems, so it has become part of a politics game.There have been several fires across the country caused by the use of mobile phones. A gas station exploded when its driver used his mobile phone while filling up the gas, causing many people to die.
When the jamming device is in working state, it can make the mobile phone transceiver signal function within the specified range fail, unable to dial out and dial in, so as to achieve the purpose of mandatory prohibition.It can be used in various places such as examination room, meeting room, gas station, oil depot, church, hospital, court, military center, library, movie theater, etc.
While jamming isn’t anywhere near shooting, the provocative activity “could lead to an escalatory pattern that could be negative for both sides,” and the US will “not look kindly” on the practice, according to an expert.US officials told the Wall Street Journal early in April that intelligence officers detected China moving radar and communications jamming equipment to the South China Sea.
