Abstract
The user inclines the apparatus () according to the pitch () and roll () axes to produce inclination signals (θ, φ) which are transformed into corresponding command setpoints (θ, φ) for the drone () in terms of attitude of the drone according to the pitch () and roll () axes of the drone. The drone and the apparatus each determine the orientation of their local reference frame (XYZ; XYZ) in relation to an absolute reference frame linked to the ground (XYZ), to determine the relative angular orientation of the drone in relation to the apparatus. Then, the reference frame of the apparatus is realigned on the reference frame of the drone by a rotation that is a function of this relative angular orientation. The realigned values thus correspond to user commands referenced in the reference frame of the apparatus and no longer in that of the drone, which allows for more intuitive piloting when the user is watching the drone.
