SonicFly drone uses rotor noise to track other aircraft without GPS or cameras
Researchers have created SonicFly, a drone that tracks other flying objects by monitoring rotor sounds instead of relying on cameras or GPS. During trials, the device utilized four microphones to pinpoint and follow sound sources, maintaining an average accuracy error of just 1.34 meters. This innovation is expected to be useful for drone swarms, delivery operations, and search-and-rescue efforts, especially in areas where GPS or standard communication signals cannot reach.
