Ukrainian company Ptashka Drones has equipped its FPV drones with microphones to detect targets by sound. The UAVs have also been given a function which allows several drones to remain on standby and respond quickly when a target appears.
“At a distance of 200 m, you can clearly hear a car moving along the road through the microphone,”
a Ptashka Drones representative said.
The amount of time a drone can remain in standby mode depends on its modification, battery capacity and distance from the operator. For example, the Ptashka 15-O30 km can remain in ambush mode for up to five hours after landing 25 km from the operator.
“You can control one selected drone and listen to what is happening through headphones, while the others display a light indicator showing the sound level,”
the company explained.
The Multizhdun feature allows an unlimited number of UAVs in standby mode to be connected to a single ground control station.
Ptashka Drones manufactures radio-controlled and fibre-optic FPV drones. Its range includes 10-, 15- and 17-inch UAVs. The company also develops counter-UAV systems, including handheld and drone-mounted net guns.
Earlier, Ukrainska Pravda reported on tests of Ukrainian systems for detecting FPV drones, including acoustic detectors. One of the developers said that, depending on the size of such a system, it can detect a drone by sound at a distance of up to several hundred metres.
