Abstract

In recent years, study of location identification by mobile phone has been attracting a lot of attention. Especially, GPS contents of mobile phone are increasing for the purpose of various kinds of applications, such as games, navigations and etc. So far, many investigations have been carried out for GPS performance by conventional GPS devices, but few people study mobile phone GPS performance. In this paper, we measured and examined the performance of mobile phone GPS using various types of terminals of different venders under some environments. As for the performance improvement, we propose an efficient method and evaluate it for the results including distance errors and direction errors of GPS. The reduction methods for such errors applying to the group characteristics of mobile phones are also described.
