Hybridization with Localization Information from Wireless Communications Systems

Kurzfassung

The fastest growing market segment for Galileo and other global navigation satellite system (GNSS) receivers are mobile phones. Users want to experience seamless location based services (LBS) no matter if they use them outdoors, in cities or indoors. To achieve this, hybridization of GNSS navigation signals with localization information from wireless communication systems is essential. Modern mobile phones are equipped today with several wireless communciation technologies that can provide localization information. In this chapter, we discuss localization information from wireless communication systems, e.g., proximity information, received signal strength, time of arrival, fingerprinting, and assisted GNSS. We further evaluate hybridization methods for GNSS and localization information from wireless communication systems, e.g., Gauss-Newton algorithm and extended Kalman filter. Additionally, we consider cooperative hybridization and error mitigation through hybridization. To conclude, hybridization of GNSS with localization information from wireless communication system is necessary for a seamless user experience of LBS.
