The article describes the modernization of Unmanned Aerial Vehicle (UAV) to perform observations of satellites. The technical requirements applied to the device and the parameters of the payload and its parameters are verified. Various models used for aerodynamic calculations are displayed and their pros and cons are revealed. Various methods of constructing solid-state models are also displayed. Several different shapes of the dome for equipment placement are proposed. The optimal shape of the dome was chosen based on the results of calculations on the pressure distribution on the body. The angle of attack was chosen based on the calculation of the resistance and lift forces.
