“…EGNOS is a European system based on the transmission of data using three geostationary satellites. In addition to EGNOS, the main SBAS group includes the US WAAS (Wide Area Augmentation System), Russia's SDCM (System of Differential Correction and Monitoring), Japan's MSAS (Multi-functional Satellite Augmentation System), India's GAGAN (GPS-Aided Geosynchronous Augmented Navigation System), China's Beidou SBAS BDSBAS, and Australia's SouthPAN (Southern Positioning Augmentation Network) [5]. With real-time transmitted data, EGNOS can significantly improve the accuracy of autonomous positioning using code-based observations [6][7][8].…”

The potential for the use of smartphones in GNSSs (Global Navigation Satellite Systems) positioning has increased in recent years due to the emergence of the ability of Android-based devices used to process raw satellite data. This paper presents the results of a study on the use of SBAS data transmitted by the EGNOS (European Geostationary Navigation Overlay Service) system in GNSS positioning using a Xiaomi Mi8 smartphone. Raw data recorded at a fixed point were used in post-processing calculations in GPS/EGNOS positioning by determining the coordinates for every second of a session of about 5 h and comparing the results to those obtained with a Septentrio AsteRx2 GNSS receiver operating at the same time at a distance of about 3 m. The calculations were performed using the assumptions of the GNSS/SBAS positioning algorithms, which were modified with carrier-phase smoothed code observations and the content of the corrections transmitted by EGNOS.
