Abstract
GPS/GNSS positioning is one of the most used smartphone features traced back to 1999. This feature has been utilised by billions of smartphone users in the last few decades, primarily for meter-level navigation purposes. In recent University of Otago research, we show that it is possible to achieve centimetre-level positioning precisions with a mass-market Android smartphone. This research finding opens up a potential for accurate smartphone positioning in various applications, such as for autonomous vehicles, earth deformation monitoring, car lane keeping, construction engineering, surveying, etc.
