The increasing popularity of drones and their availability to customers has led to the emergence of funds that can protect private / commercial / state property from these potentially dangerous flying machines. To date, a considerable number of UAV clearance systems have been created, but most often they are effective only at a short distance. This fact not only reduces the effectiveness of the protective measure, but also increases the danger if the intruder transfers explosive substances. That’s why the Australian company DroneShield developed the Dronegun electronic gun, which can stop an unmanned aerial vehicle at a distance of up to 2 km. Despite its frightening appearance and weight of 6 kg, Dronegun, like most counterparts, does not destroy the drone, and with the help of a directional emitter it blocks signals from a hiding operator. Since the aircraft ceases to receive commands and cannot determine its place using GPS or GLONASS, it either returns to its original position, from where it took off (thereby there is a chance to find a person-intruder), or begins to sink to the ground. The operation of the electron gun does not physically damage the flyer and does not allow you to remotely send a command about self-destruction. The manufacturer plans to sell its invention worldwide, but its cost has not yet been announced.
