|Abstract:||A novel joint tracking loop for multifrequency signals transmitted from a GNSS satellite is proposed. The method makes use of a beamforming technique that is conventionally applied to antenna arrays, but used here to combine signals of several frequency bands. It increases the robustness to deep amplitude fades and interference of jammers, while preserving the conventional receiver architecture including the correlators, discriminators, loop filters and carrier aiding. Doing so certifications of Rx processing in safety-critical applications can be performed by following well established procedures. In the case of no interference the Signal-toNoise-Ratio (SNR) is amplified by the number of employed multifrequency signals.|
