The paper presents a characterization of the signal anomaly of SVN 49. A mathematical model is developed to relate the observed multipath to the internal signal reflection. The analyses provided in the paper are based on measurements, which have been collected during a dedicated tracking campaign with a 30m-dish antenna. Data on the L1 and L2 frequency have been collected with four different receivers. In addition, IQ samples have been recorded directly with a spectrum analyzer. The multipath combination of the receiver measurements on L1 and L2 is analyzed to demonstrate the effect of the signal reflections on different correlator spacings. The capability to suppress the signal reflection with receiver's multipath mitigation methods is demonstrated. Finally, preliminary estimates of the attenuation, delay and phase-shift over elevation are obtained from an IQ sample analysis.
