Abstract
As for the satellite based positioning system GPS and GLONASS has been used mainly, but QZSS and Galileo has come to be used in recent years. Also, GPS has increased the satellite to send a new positioning signal L2C. Therefore, the satellite positioning can be expected to obtain a good observation data than ever, while it is necessary to remove the satellite signal including the multipath. The authors have verified a method for determining of satellite signal of multipath using the L1C/A and L2P signal strength and the difference of phase change between satellite signal L1C/A and L2P by GPS and GLONASS in previous studies. In this study, newly added L2C signal of GPS and L1P signal of GLONASS, then verified whether detectable satellite signal including a multipath from the actual observed data. As a result, satellite signal affected by multipath can be detected similarly to the conventional positioning signal. In addition, the effect of the increase of multipath detection indicators was confirmed by the percentage of fix solution and positioning accuracy.
