EXPERIMENT OF THE HIGH ACCURACY POSITIONING BY QUASI-ZENITH SATELLITE MICHIBIKI OF JAPAN

摘要

In 2010, the Japanese government launched Quasi-Zenith Satellite, and the main roles of Quasi-Zenith Satellite are augmentation and complementation of GPS. Augmentation of GPS is a reinforcement signal which improves positioning using compensation information, and Quasi-Zenith Satellite broadcasts LEX signal and L-1SAIF signal which are reinforcement (augmentative) signals. Especially, the LEX signal is expected noting that it will be able to perform positioning of the centimeter class. This paper describes the research of an experiment which used the LEX signal.
