Breaking the One-Meter Accuracy Level with Smartphone GNSS Data
Abstrak
Smartphones are usually equipped with simple, cost-effective GNSS chips and antennas. They provide mainly single-frequency, low-quality, and challenging GNSS measurements. We demonstrate the difficulties of processing raw GNSS data from Android devices and introduce solutions to break the one-meter accuracy level with smartphones and Precise Point Positioning. With the logged data of a Samsung Galaxy S23+ and a Google Pixel 7 smartphone, a horizontal position accuracy of around one meter and a few decimeters was accomplished, respectively. These results were achieved after about two minutes of convergence time with our open-source software raPPPid in quasi-real-time settings. Furthermore, the corrections provided by the Galileo High-Accuracy Service proved to be sufficient to achieve sub-meter accuracy with smartphones.
