In the modern world, UAVs (unmanned aerial vehicles) are increasingly used in everyday life in solving our civilian tasks. One of the main applications of UAVs is
data collection with their reference to a given coordinate system. For example, for the task of aerial photography, it is necessary to accurately link each image to the
global coordinate system. In addition to the exact location of coordinates, it is worth the exact movement of a given route, to collect data of exactly those places that are needed. Thus, it is very important to ensure the minimum deviation of the UAV from the given route under the conditions of external disturbances (wind loads) acting on it. The article describes a procedure for assessing wind speed and direction for a UAV control system using the SPSA method. The results of simulation modeling of the operation of the algorithm, confirmed during field tests on an ultralight UAV with an ardupilot autopilot, are presented.
