Analysis of DME/TACAN Interference on Satellite Navigation in the Lower L-Band

Kurzfassung

In March 2009 the German aerospace centre (DLR) has measured DME interference over the European DME hot spot in various altitudes. The aim of these measurements was to determine the interference situation in the GALILEO E5 and GPS L5 bands caused by distance measuring equipment (DME) stations on the ground. First results at the hot spot show a strong reception in low altitudes of a small number of stations. By increasing the altitude the number of visible stations is increased dramatically. The general power level hence is reduced. The general goal of this activity is to derive a DME interference model.
