Smartphone application GPS performance during various space weather conditions: A preliminary study

Handheld GPS devices are nowadays increasingly replaced by smartphones with Android-based GPS applications. Moreover, it becomes a matter of concern, given that the position derived with this application is taken for granted, with over- reliance from users not aware of potential misleadings and errors the position can befall. For this purpose, two mobile devices were fitted at fixed point in south Croatia, previously determinated by differential means. At this obstruction-free location, positioning applications are launched and received positions have been recorded during hours. After several recordings and data post-processing, analysis have been carried out in order to determine position deviations in all directions. Here, the results obtained are presented, giving an insight in GPS positioning accuracy at the time of observation. The paper represents the basis for further work, where the same cell phone application will be elaborated in various, more critical situations.
