In recent years, Geospatial Information Systems (GIS) is applied in many applications. However, the cost of data acquisition by traditional survey is always a limitation for GIS applications. The Mobile Mapping System (MMS) is a solution to improve this situation. The absolute position of the interested object can be quickly acquired through direct geo-referencing (DG) because of its high mobility and automation. Nowadays the most common technologies used for positioning and orientation of a mobile mapping system include using Global Navigation Satellite System (GNSS) as a major positioning system and Inertial Navigation System (INS) as the major orientation system. This study develops the Portable Mobile Mapping System (PMMS) that has high autonomy because of the less limitation of topographic. The calibration parameters of PMMS are calibrated by Two-Step. And the performance of the PMMS DG is analyzed by about 10-20 control points that are built by the other high accuracy surveying methods. Generally speaking, the preliminary results presented in this study illustrate the performance of those PMMS DG with conventional DGNSS reach 10cm level at 20 m camera to object distance.
