This paper features an experimental Galileo PRS receiver with a novel BOC tracking method and interference mitigation algorithms in time, frequency and spatial domain. The modified BaSE-II hardware architecture is outlined including a newly designed miniaturized 2x2 array antenna. A new, reliable and robust BOC tracking method is presented that fully exploits the subcarrier accuracy and allows reliable, fast and robust detection and correction of false locks to side peaks. Finally the implemented interference mitigation techniques are described with keeping the special PRS requirements in mind.
