Location awareness and navigation are becoming one of the most important features in mobile phones and Smartphones. Personal navigation and location based services are enlarging the scope of mobile applications. GPS (Global Positioning System) is the most efficient positioning technology. Thanks to the reduction in the size of the GPS receivers and the integration of GPS with mobile phones, GPS is one of the most important service providers in LBS (Location-Based Service). By the way, since mobile phones and Smartphones usually have relatively low cost GPS chips, the performance of locating accuracy is highly dependent on environmental factors.
