Research and creation, adjustment and testing of rotor-type unmanned aerial vehicles (UAVs) in the conditions of countering radio interference were carried out in the work. The problem solved during the construction of such a UAV is the provision of stable flight in the area of operation of systems that create radio-electronic interference (hereinafter – REI). The designed UAV is capable of automatically carrying a payload of 2.0–2.5 kg at a speed of 40–45 km/h for 25–30 min under the control of the Pixhawk flight controller. The article indicates the expediency of using a mathematical model based on the third version (order) extended Kalman filter algorithm to ensure flight stability in difficult meteorological conditions, including strong gusty winds (up to 12–13 m/s). An experimental study of the flight of the designed copter was carried out according to the lua script, which allows control in conditions of loss of communication with navigation satellites. It is shown that in this case, the UAV returns to the starting point using an algorithm that works according to the readings of the barometer and magnetometer. A script has been developed that allows the UAV to perform stable flight in the event that the navigation commands are replaced by REI systems. The work is of practical interest, since the designed multicopter can be used in the areas of system operation that create strong radio-electronic interference.
