| Outline of Final Research Achievements |
In this study, field tests to evaluate the accuracy of the QZSS (Quasi-Zenith Satellite System) were conducted in the experimental site set up in Cryptomeria japonica plantation forests with an area of 0.24ha. As a result, there was little improvement of positioning accuracy when the complementary signal was used. It was also found that there was little difference in the positioning accuracy between the QZSS and conventional MSAS when the augmentation signal was used. However, the reception rate of the QZSS signals from the higher elevation angles was found to be higher than the MSAS signals with the lower and medium elevation angles. Therefore, GNSS receivers with the multipath rejection technology that blocks the signals from the lower and medium elevation angles are expected to improve the positioning accuracy.
