Abstract

A multicopter including motors driving propellers, a first interface providing parameters including: a position of a center of gravity of the multicopter, time derivatives, an orientation of the multicopter and its time derivative; a second interface providing power generated by respective propellers; a first unit, based on the parameters, a provided model that describes dynamics of the multicopter, and an estimation of a force wrench acting externally on the multicopter, the estimation based on based on the model, determines horizontal components of a relative speed of the multicopter in relation to air; a second unit which, based on the horizontal components and power, determines a vertical component of the relative speed; a third unit which, based on the horizontal components, vertical component, and parameters, determines a wind speed in an inertial system; and a storage unit to store wind speeds and/or a transmission unit to wirelessly transmit the wind speeds.
