Using electronic countermeasures, by emittingelectromagnetic waves, covering and suppressing the UAV's communication frequency band, as shown in the figure, remote control positioning three main channels. When the drone is disturbed, it loses contact with the ground controller and is forced to land or return to the same place.
Frequency band
1 GPS channel When the GPS channel is turned on, the interception system will emit electromagnetic waves to the UAV, which interferes with the normal GPS signal reception of the UAV and causes the UAV to lose GPS navigation and force it to land.
2 The 2.4G channel and 5.8G channel are two channels that the pilot uses the remote control in his hand to issue commands to the drone to control the drone, and also use these two channels to receive the image signals and data sent back by the drone. The 2.4G channel is currently the most used in the drone market. Many drones such as DJI use this channel. On this basis, Spear Falcon suppresses these two channels so that the pilot and the drone can communicate. The connection between the pilots was disconnected and the pilot could no longer control the aircraft.
