VERIFICATION OF COMBINED EFFECTS OF QZSS IN HIGH PRECISION POSITIONING WHEN DRIVING ON STREETS

Abstract

 Currently, satellite positioning technology is drawing attention with the aim of putting autonomous driving into practical use. Therefore, this study did verification of the combined use of QZSS in satellite positioning during street driving. As a result, it was shown that the fix rate was improved by 36% by using QZSS together in this case.From these results, the combined effect of QZSS was clearly recognized, but the fix rate was not high in any case. Therefore, analysis from the positioning results revealed that the increase in the number of satellites strongly contributed to the improvement of positioning accuracy.
