Initial performance evaluation of centimeter‐class augmentation system using Quasi‐Zenith Satellite System

On September 11, 2010, the Quasi‐Zenith Satellite (QZS) “Michibiki” was launched from the Tanegashima island as the first satellite for positioning in Japan. We have attempted to fix positions using LEX data with centimeter‐class augmentation service for centimeter‐level positioning augmentation signal via Michibiki. The authors tried to fix positions by using LEX data at a stationary point and in a moving car in real time and with postprocessing. They could confirm no more than 2.22 cm as the average positioning error and discrepancy of postpositioning.
