A case study of smartphone-grade GNSS positioning performance analysis during a massive geomagnetic storm

dr. sc. Renato Filjar, prof. v. š.

Sažetak

The presented research addresses the problem of the GNSS positioning performance during severely disturbed
geomagnetic and ionospheric conditions on single-frequency multi-GNSS receivers commonly found in smartphones. The GPS system provides a robust positioning performance, while Galileo and GLONASS, in particular, perform less efficiently in northern Croatia during a massive ionospheric storm outbreak
in May 2024. As the result, the utilisation of the multi-GNSS approach in serving the Location-Based Services (LBS) applications is recommended.
