A real time snow removal truck support system was developed that integrates GNSS including Quasi-Zenith Satellite System (QZSS) and Mobile Mapping System (MMS). In the verification, this system was practically installed on a snow removal truck, then Centimeter Level Augmentation Service (CLAS) positioning accuracy of QZSS and the accuracy of 3D road facilities data by MMS were verified, furthermore a guideline for the development of an integrated system of both QZSS and MMS were clarified. On the highway lane with good visibility in the sky, RTK positioning (FIX type) information was normally received and processed, and also simultaneously processed in real time with 3D road facility information.
