Measuring the interaction of wind turbines with terrestrial navigation and radar systems deploying UAS

We describe the development of a system for measurements of electromagnetic field strength distributions and on-site antenna calibrations based on an unmanned aerial system (UAS). The commercially available octocopter was improved by a state-of-the-art GNSS navigation system and a shielding against electromagnetic harsh environments. We have designed, built and tested the FPGA-based data logging hardware as well as several RF frontends and antennas to be mounted on the UAS. We show first applications of our UAS measuring the interaction of wind turbines and terrestrial navigation systems such as DVOR and radar systems used for air traffic surveillance.
