GPS Signal Reflection in the Vicinity of an Aircraft - a Statistical Approach

Christian Discher, Ralf Stolz and Andreas Lipp

Abstract:	Investigations in the past have shown that multipath propagation due to the aircraft structure itself could have a non-negligible impact on GNSS measurements. Therefore a study was carried out. It was the aim of this study to obtain a statement on the statistical occurrence of multipath propagation in the vicinity of the aircraft. For this purpose a simulation tool has been developed in cooperation with the EUROCONTROL Experimental Centre. The results were verified by evaluation of real flight data sets from EUROCONTROL’s SAPPHIRE database. The paper details the used simulation models as well as the results with regard to the prediction of signal reflection by the aircraft surface. Comparisons between the predicted occurrence of multipath and real flight data show a good correlation.
