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 accessory includes a coupling part configured for the removable coupling of the accessory on the reception support, a connector configured for the electrical connection of the accessory to the reception support, and at least one sensor configured to generate an output signal representative of a physical property. The connector is directly connected at the output of the sensor to transmit the output signal from the sensor to the reception support without processing of the output signal between the sensor and the reception support.

Abstract: A primary user terminal is interfaced with the drone so as to constitute a local network of the infrastructure type, where the drone is configured as an access point (AP) and the primary user terminal is configured as a mobile station. The primary user terminal comprises an adaptive software program able i) to generate piloting and control instructions to be transmitted to the drone, and ii) to establish a connection to the local network and to register the primary user terminal into a registration table of the drone. The network further comprises at least one secondary user terminal with an applicative software program adapted to establish a connection to the local network and to register the secondary user terminal into the registration table of the drone with a hierarchized management of the rights with respect to the primary terminal.
