Navigation Support of UAVs for Performing Fly-by Radio Measurements in Urban and Industrial Development
Electromagnetic fields created by various radio transmitting objects can affect human health, the natural environment and equipment that has a built-in electronic control system. Electromagnetic pollution occurs mainly in cities and industrial areas. To assess the existing electromagnetic environment, a flyby method of measurements using unmanned aerial vehicles (UAVs) of the multicopter type can be used, which provides high information content and a small error in the results obtained. At the same time, in conditions of dense urban and industrial development, it is necessary to ensure autonomous UAV navigation, while reducing the accuracy of satellite navigation systems, as well as meeting safety requirements during flights. The results obtained show that when performing antenna measurements at short ranges, it is advisable to use onboard optical sensors that supplement the data from the GLONASS and GPS satellite navigation systems.
