ABSTRACT
Positioning and navigation in urban environments has been challenging due
to partial unavailability of GNSS (Global Navigation Satellite Systems)
measurements. The increasing availability of Wi-Fi (Wireless Fidelity) and
UWB (Ultra-Wide Band) measurements in indoor as well as outdoor urban
environments provides additional measurements that could be used for
localization. It has been demonstrated that sharing of information among
multiple platforms can help to overcome the challenges of precise
localization in GNSS challenging environments. This information sharing
strategy referred to as ‘Cooperative Localization (CL)’ has been shown to
provide superior localization solution in GNSS available environments. CL
refers to simultaneous positioning of all dynamic platforms in a connected
network where each node shares information about its own state and some
relative information about other nodes. A CL framework that combines
information exchange among multiple platforms and measurements from
GNSS, UWB and Wi-Fi can potentially solve some of the positioning and
navigation challenges in urban and indoor environments.
