The study and implementation of mobile GPS navigation system based on Google Maps

Google Maps API provides a number of utilities for adding individual content to the Google map and various web map applications can be explored based on Google Maps API. Assisted global positioning systems (A-GPS) is adopted by mobile operation companies as the highest accurate positioning way in mobile location based services. This paper proposes a solution of mobile navigation system that realizes such functions as Google map browse and query, bus lines search, the rapid local positioning on your mobile phone etc. In this paper, we discuss the system technical scheme and the key realization technologies. At last, the test result is displayed on Nokia N73. The results prove that the solution of mobile navigation system based on Google Maps is feasible and valid, and it can be installed in PDA, mobile phones and other portable information terminals.
