Abstract (in Japanese) (See Japanese page) 
(in English) In recent years, LBS attracts attention due to the spread of mobile phone GPS, and it is applied to various applications. Now, when mobile phones have become ubiquitous terminals, many mobile phone GPS terminals may be unevenly distributed within local locations. Our study examines the error characteristics of them that are located between short distances and we were able to establish that improvement in the error characteristics is possible by adding GPS errors. In this paper, we consider that positioning errors in GPS terminals depend on the difference of number of satellites to use for positioning calculation and satellite numbers. In addition, we investigate the effect by changing them and perform theoretical analysis of GPS errors in order to improve the error characteristics based on the coordinates of satellites.
