Characterization and Mitigation of Multipath for Terrestrial based Aviation Radionavigation

In this contribution we give a comprehensive overview of multipath propagation and its effects on current and future L-band terrestrial radionavigation devices. We characterize the line of sight and multipath propagation between a ground station transmitter and an aircraft based on measurement data. We then present different methods to mitigate effects of multipath propagation and limit the resulting errors.
