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.

这项研究的目的是研究使用准重新纳思卫星系统（QZSS）的下一代导航系统的可能性，据说GPS数据的准确性会提高。我们将四个GPS设备放在汽车上，并获取了四种GPS数据，包括QZSS。然后比较这些数据的准确性。结果，发现来自QZSS的GPS数据较少准确，并且需要用于下一代导航系统的QZSS校准方法。
