Abstract:
Just a couple of years ago, GNSS (Global Navigation Satellite Systems) were available only for a narrow group of users. Currently, with the outbreak of mobile devices, they are accessible to anyone and everywhere. Urban navigation or searching for POIs (Points of Interest) had become an everyday activity. With the availability of consumer electronics and wireless technologies, each user can obtain information considering his or her location even in an unknown environment. Additionally, network operators and service providers utilize this location-based information for monitoring and maintenance purposes. This paper is focused on a study, considering the DOP (Dilution of Precision) and pseudorange error estimation in case of Android-powered smartphones operating outdoors. It describes a measurement campaign, carried out in varying urban environments, with two types of excursions (by car and bicycle), including two popular consumer devices from different manufacturers. Based on this, r
espective conclusions and remarks are given. This work aims to aid not only users, but also application developers as well as device manufacturers and retailers, when it comes to providing precise and reliable products and services.
