Abstract
The inertial unit, IMU, of the drone is mounted on a main circuit board. The IMU () includes an internal temperature sensor delivering a chip temperature signal (θ°). A heating component () 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 (-) receives as an input the chip temperature signal (θ) and a set-point temperature signal (θ°), and delivers a piloting signal (_) 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.
