Wind speed and direction experienced by the UAV at altitude is determined by placing an accelerometer, gyroscope and compass on the UAV. A change in velocity experienced by the UAV is determined by the accelerometer. An orientation relative to a reference plane and an angular velocity experienced by the UAV is determined by the gyroscope. A magnetic bearing of the UAV is determined with the compass. A roll and pitch exhibited by the UAV is determined as a function of the change in velocity, orientation and change in angular velocity. Projected roll and projected pitch vectors onto a horizontal plane cutting through the center of rotation of the UAV are determined as a function of the roll and the pitch. The wind speed of the wind experienced by the UAV is determined as a function of the projected roll vector and projected pitch vector. The wind direction is determined as a function of the projected roll vector and projected pitch vector and the magnetic bearing of the UAV.
