In the near past, GNSS (Global Navigation Satellite Systems) were only offered for a narrow group of recipients. Nowadays, thanks to mobile devices, they are available to anyone and everywhere. Personal navigation, searching for POI (Point of Interest), etc., had become a basic essential activity. Thanks to the widespread and availability of smartphones each user can obtain information considering his or her location even in an unknown environment. Furthermore, network operators and providers use 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 mobile devices operating outdoors. It describes a measurement campaign, carried out in varying urban environments while driving a car, including two popular consumer devices from different manufacturers running Android OS. Based on this, respective 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.
