Breaking the One-Meter Accuracy Level with Smartphone GNSS Data

Blog Article

Smartphones are usually equipped with simple, cost-effective GNSS att nighthawk hotspot 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 stickers logos dallas cowboys proved to be sufficient to achieve sub-meter accuracy with smartphones.
