<p>A system is described, for measuring the wind speed at a certain height, comprising at least one unmanned aircraft (1) immersed in a field of motion (2) determined by such wind, such unmanned aircraft (1) being equipped with first on-board processing means adapted to operatively interact on a propulsion system and/or on a flying guiding system of such aircraft (1) to modify its flight attitude depending on external perturbations exerted by such wind present in such field of motion (2) to keep a centring of such aircraft (1) along at least one reference flying trajectory (3) passing through one or more following flight attitudes (l,i l,m, l,f) corresponding with different flight heights above a reference level (S), and detect attitude data related to such attitudes (l,i, l,m, l,f) at such relative flight heights.</p> |
