Abstract

This publication describes an end-to-end model to generate Distance Measurement Equipment (DME) signals as an interference source to airborne Global Satellite Navigation Systems (GNSS). Both satellite navigation systems, the Global Positioning System (GPS) and GALILEO, use the lower L-band 1 for wideband navigation services and are sharing the same frequency band with DME. Any GNSS Receiver operating in the mentioned bands will receive DME signals and will have to deal with them as interference. This publication describes a model to rebuild the measured DME signals at the receiver input to allow simulations of the interference effect. Prior to this work we only found models based on propagation estimation. No model existed which is based on real world measurements of DME signals. Thus, the German Aerospace Center (DLR) has car- ried out a Fight measurement campaign at the European DME hotspot near Frankfurt (Main), Germany. From the data of the measurement campaign we have developed the new model. This measurement based model is much more accurate than the existing models since it accounts for the propagation and the DME transmission and the GNSS receiver antenna effects. We provide this model to the community to allow a more realistic forecast of the DME-GNSS interference situation
