    Abstract: The invention relates to a method, implemented in a drone piloting device (16), of loading satellite ephemeris data, the drone (10) comprising a geolocation module, the method comprising a step of establishing a communication between the piloting device (16) and the drone (10) according to a given communication mode. The method further comprises the following steps implemented in the piloting device: loading ephemeris data (E26) from a remote server (32) connected to a communication network (30), and sending the loaded ephemeris data (E25) to said drone. The invention has also for object a method of loading satellite ephemeris data, implemented in a drone, for updating ephemeris data of a geolocation module.

    Abstract: The inertial unit, IMU, of the drone is mounted on a main circuit board. The IMU (26) includes an internal temperature sensor delivering a chip temperature signal (θ°chip). A heating component (36) is mounted on the circuit board near the IMU, and it is provided a thermal guide, incorporated to the circuit board, extending between the heating component and the IMU so as to allow a transfer to the IMU of the heat produced by the heating component. This thermal guide may in particular be a metal planar layer incorporated to the board, in particular a ground plane. A thermal regulation circuit (44-62) receives as an input the chip temperature signal (θchip) and a set-point temperature signal (θ°ref), and delivers a piloting signal (TH_PWM) of the heating component, so as to control the heat supply to the IMU. It is in particular possible to use this fast increase in temperature to perform a complete calibration of the IMU in a few minutes.

    Abstract: A vertical-view camera (16) delivers an image signal (ScamV) of the ground overflown by the drone. Gyrometric sensors (102) measure the Euler angles (φ, θ, Ψ) characterizing the attitude of the drone and delivering a gyrometric signal (Sgyro) representative of the instantaneous rotations. Rotation compensation means (136) receive the image signal and the gyrometric signal and deliver retimed image data, compensated for the rotations, then used to estimate the horizontal speeds of the drone. The camera and the inertial unit are piloted by a common clock (160), and it is provided a circuit (170) for determining the value of the phase-shift between the gyrometric signal and the image signal, and to apply this phase-shift value at the input of the rotation compensation means (136) to resynchronize the image signal onto the gyrometric signal before computation of the retimed image data.
