Abstract

This Diploma Work proposes a method to estimate the presence of multipath in a GPS satellite signal. The method can provide a lower bound on the number of reflections, the attenuation factor of the individual paths with respect to the line-of-sight path. For the estimation, the satellite signal carrier is reconstructed by adding the phase feedback of the carrier tracking loop, and the I and Q outputs back together. The estimation technique is validated with measurements taken on the Spirent Constellation Simulator which is operated at DLR Oberpfaffenhofen. Measurements with the present GPS constellation which were done in an urban surrounding in Munich suggest that the discovered eff�ect is also present in reality.
