Abstract

Software based cellular location systems for accurately determining the location of a wireless cellular device is becoming one of the key dierentiator in an increasingly crowded personal communication market. New location-based services are the long awaited killer application for the wireless industry, according to analysts. Current and future development plans foresee that providers can deliver location-based ser- vices to standard mobile phones and that the users through their wireless hand-set can now accurately locate themselves and tap into new applications like mobile yel- low pages, concierge services, roadside assistance, location sensitive billing, personal navigation and tracking services. In US, the development of these services is be- ing encouraged by the FCC E-911 mandate, all US wireless operators will begin to provide the location of mobile emergency callers to safety ocials and emergency dispatchers. There are many regulators in other countries worldwide that are be- ginning to explore mandating wireless location in this way too, including Europe [1]. In this paper we show how, providing the users of terminals able to deal jointly with GNSS signals and cellular positioning signals it possible to improve the geometrical Dilution of Precision related to the navigation solution. A theoretical framework is dened in order to deal with the hybrid localization system, and simulation results are presented.
