Abstract (in Japanese) (See Japanese page) 
(in English) In order to estimate user’s position, a GPS receiver has to receive signals from at least four observable satellites. However, in urban area, the number of the observable satellites will decrease because urban area has many buildings. In such cases, position estimation cannot be performed well. So, our research considers the position estimation in case the observable satellites are decreased. Many of vehicles have wheel rotation sensors which can measure traveling distances. By both a previous position which are estimated under good GPS condition and the distance sensor, our proposal estimates the next position. By experimental results, we will show our effectiveness of the proposal.
