Abstract
Apparatuses and methods are described for determining displacement and/or rotation of a Unmanned Aerial Vehicle (UAV), including, but not limited to, determining a first Time of Flight (ToF) for audio signals transmitted by an audio transmitter of the UAV and received by a first audio receiver of the UAV while the UAV is in motion, determining a second ToF for the audio signals transmitted by the audio transmitter and received by a second audio receiver of the UAV while the UAV is in motion, and determining the displacement or the rotation of the UAV based, at least in part, on the first ToF and the second ToF.
