Keywords:QZSS, Vehicle Position Detection, Positioning accuracy

At present, technical development is being pursued with the aim of commercializing automatic driving. GNSS is at the core of the technology for determining the position. Therefore, in this study, the application of the vehicle position detection of satellite positioning using QZSS, which is being developed and maintained in Japan, and to verify its applicability. As a result, it was clarified that the use of multiple QZSS in suburbs greatly improved the accuracy, but that the use of QZSS with low elevation angles in urban areas could lead to deterioration of accuracy.
