Assessment of a dual-frequency multi-GNSS smartphone for surveying applications

Abstract This study assesses the application of a smartphone with dual-frequency multi-constellation GNSS (Global Navigation Satellite Systems) receiver in surveying. Measurements are made Pixel 5 from manufacturer Google LLC. The recorded satellite data is evaluated post-processing positioning methods based on code and phase observations. focus here led achievable accuracies resulting deviations different estimated solutions reference points serving as ground truth. It could be shown that 5, although it enables recording two frequency bands, can only used to limited extent practical surveying tasks because does not met accuracy requirements centimetre range our experiments. low quality measurement problematic, which why over bands observations possible extent. Nevertheless, long observation times, results less than half metre achieved smartphone. Thus, for applications lower such acquisition Geographic Information Systems (GIS).
