Abstract: A drone including a barometric sensor adapted to deliver a drone altitude signal; a sensor for measuring the attitude of said drone, adapted to estimate at least one angle of attitude of the drone, and altitude determination means adapted to deliver a drone altitude value, expressed in an absolute terrestrial reference system. The drone includes a relative wind speed sensor adapted to measure the relative wind speed and the altitude determination means includes a device for memorizing predetermined altitude compensation data, an altitude estimator receiving as an input the signals delivered by the attitude measurement sensor and by the relative wind speed sensor and by the barometric sensor and combining these signals with the altitude compensation data memorized in the memorized device to output the estimated drone altitude value.

Abstract: The invention relates to a method for capturing a video using a camera on board a fixed-wing drone, the camera comprising an image sensor, the drone having, during flight, a drift angle between the longitudinal axis of the drone and a flight direction of the drone. This method comprises: determining the drift angle of the drone; and obtaining video by image acquisition corresponding to a zone with reduced dimensions relative to those of the image sensor, the position of the zone being determined as a function of the drift angle of the drone.

Abstract: The invention relates to a rotary-wing drone (10) comprising a drone body (30) that comprises an electronic circuit board controlling the flight of the drone, four link arms (36) comprising a propulsion unit (38) at their ends, two propulsion units each having a propeller (12) that rotates in the clockwise direction and two propulsion units each having a propeller that rotates in the anticlockwise direction, the propulsion units that have propellers that rotate in the same direction being positioned on the same diagonal line. The drone comprises a propulsion support (32) comprising the link arms (36) and a central hub (34), two pairs of symmetrical link arms each extending on either side of the central hub, the central hub (34) being capable of being coupled to the drone body (30), and the propulsion support (32) having at least one torsional bending direction extending in the horizontal plane.
