| Abstract(in English) | We conducted high-precision positioning experiments using QZSS (Quasi-Zenith Satellite System) and a dual antenna GPS receiver (Septentrio: Aste-Rx m2a) to help position visually impaired people walking outdoors and provide position information to emergency personnel in the event of a large-scale disaster. To capture the centimeter-level positioning augmentation information from QZSS in real time, CLARCS (Centimeter Level Augmentation service-based RTK Correction System) via Wi-Fi developed by SPAC (Satellite Positioning Research and Application Center) was used. In this experiment, the current position and relative position between the antennas were measured using two GPS antennas attached to the subject’s shoulders to determine the direction of travel. In the outdoor walking experiment, the effectiveness and improvement points of the movement locus on the premises of Niigata University during snowfall, the round-trip walking locus when moving on sidewalks form which snow had been removed, and the walking locus around Niigata Station were examined. |
