Compatibility of wind turbines and Doppler VORs used in aviation
The prognosis tool for DVORs, which had originally been developed by Deutsche Flugsicherung (the German Air Navigation service provider (ANSP)), was revised in the “WERAN plus” project. In addition, PTB has developed a second method that physically superimposes the fields of the transmitting device and the field components reflected by wind turbines at the correct phase and derives a bearing angle error from this. e results are validated by means of measurements and electromagnetic full-wave simulations. The drone-based measurement technology and the simulation methods were developed jointly by PTB with its partners in WERAN, its predecessor project. This now makes it possible to better quantify the impact of planned wind turbines on DVORs, allowing more turbines to be approved in the future.
