To obtain indoor positioning information by GPS satellite is difficult now. The Japanese Government executed a new law NSDI (National Spatial Data Infrastructure) for a spatial information society on May 30, 2007. In this law, everybody can know positional information in real time anytime and anywhere[5]. In addition, it is necessary to keep satellite positioning for realization of seamless positioning, and to promote ubiquitous network technology [1] [4]. However, the technology has not been established yet. Therefore, Integrated Circuit Tag (IC tag) was used where GPS signals could not be received to obtain information on the absolute position. The experiment was conducted to verify the reading rate of IC tag on different types and conditions. An experiment was conducted to show position information to obtain seamlessly GPS positioning and IC tag on the GIS.
