Short summary

D-VOR transmitters are used as navigation aids in aviation. In an airborne navigation receiver, a directional information (azimuth angle) related to the position of the aircraft and the location of the transmitter can be derived. In this work, the bearing accuracy of current methods is investigated. The proposed new method reduces noise and thus yields a significant increase in accuracy. Finally, the application of this new method to real measured signals confirms the theoretical expectations.
