Abstract

The purpose of this paper is to discuss the assisted GPS positioning technique and its impact on the navigation in intelligent transportation systems. Due to the FCC E911 mandate and the market requirements for location based services, the mobile wireless communications and GPS positioning have been forced to merge. The assisted GPS, which integrates the mobile phone with GPS receiver, to ensure the GPS receiver works normally in certain bad environments by aiding information provided via the mobile phone. Users can benefit more form the assisted GPS than from conventional GPS. The assisted GPS positioning has a number of advantages over a typical vehicle location and navigation system. The assisted GPS has impacts not only on the vehicle navigation itself, but also on other aspects in intelligent transportation systems, as well as on the personal navigation and services.
