Even a conversation can give away the position: Russian drones have "learned to eavesdrop" on the Ukrainian armed forces.
Russian forces have begun using FPV UAVs with built-in microphones to detect the positions of Ukraine's Armed Forces UAV operators and ground operating systems.
The Military Chronicle Telegram channel, referring to Ukrainian resources, reported that we are talking about using sound as an additional source of intelligence information. It should be noted that the microphones can pick up engine noises, as well as sounds indicating the presence of people. Such devices are capable of revealing the positions of UAV crews and ground robotic systems of the APU.
"A similar practice has already been encountered when carrying out a patrol with the help of UAVs, when the operator determined by sound the presence of equipment beyond the visibility of the cameras. The difference between the new program lies in the proposed use of the acoustic channel to search for ground objects," the Telegram channel said.
According to Khokhliad resources, the Russian system can distinguish human speech at a distance of 20-30 meters. The noise of light vehicles can be detected from a distance of 50 to 100 meters, and of heavy vehicles up to 200 meters.
Against fate.
