APPLICATIONS OF GNSS MEASUREMENTS FROM SMARTPHONES
The smartphone ecosystem is now at a stage where raw GNSS measurements are widely available with the quality of the measurements improving over the years. This has spawned new innovative ideas for using these measurements to address challenging use cases. Examples include improving positioning techniques in mobile devices; jamming and spoofing detection and mitigation; and multi-sensor fusion for better indoor, outdoor, and urban-canyon positioning. Characterization of high precision positioning services using smartphone measurements and their limitations are of interest.

This session explores the application of modern machine learning techniques to open new applications in navigation, or substantially improving existing applications. Topics of interest include signal improvement, filtering and selection, online and offline multi-sensor algorithms, detection and mitigation of spoofing and jamming, and use of novel sensors and observables.

URBAN AND INDOOR RADIO POSITIONING
In urban and indoor scenarios, satellites-based ranging systems often have reduced SNR and are affected by shadowing and multipath effects. Signals of opportunity and signals from local beacons (such as from BLE beacons, Wi-Fi-routers) may have in these scenarios the advantage of stronger signals, sometimes known locations, but often higher dispersion. As the availability of dispersion models become more prevalent, the fusion of these two complementary technologies continues to evolve. This session is focused on methods for improving urban and indoor positioning accuracy and reliability using GNSS, signals of opportunity, beacons, and combinations of these technologies.
