英文摘要
A purpose of this study is to examine possibility of next-generation navigation system that utilized quasi-zenith satellites system (QZSS) by which it is said that accuracy of GPS data rises. We put four GPS devices on the car and acquired four kinds of GPS data including that from QZSS. Then accuracy of these data were compared. As the result, it was found that GPS data from QZSS is less accurate and that calibration method for QZSS is needed for next-generation navigation system.
