Abstract

This is a work-in-progress paper describing the methodology to acquire and process raw GNSS data from Android devices, as well as preliminary results based on measurement campaigns conducted in Finland, Togo, and Algeria. The raw GNSS data acquisition is now supported by most Android smartphones (version 10 or newer) and such data can serve as very useful research data to develop low-cost positioning algorithms as well as to do statistical analysis under various scenarios, especially when working with imperfect, inaccurate, or incomplete pseudorange data. This paper presents the methodological steps to follow in the process of data collection and provides an initial analysis of the various error models in GNSS-based positioning. The challenges and potential solutions and future steps are also emphasized.
