Abstract

Japan has been developing a new satellite based positioning system called Quasi-Zenith Satellite System (QZSS). Since improvement of positioning availability in urban area is one of the most important advantages of the QZSS, multipath mitigation is a key factor for the QZSS positioning system. Therefore, Japan Aerospace Exploration Agency (JAXA) and GNSS Inc. developed a pseudolite, which transmits the nextgeneration signal such as BOC(1,1), in order to evaluate the effect of multipath on the new signal. Flight experiments using a pseudo quasi-zenith satellite installed on a helicopter were conducted, and multipath mitigation by the BOC signal was demonstrated.
