Design and implementation of GPS&GIS -based mobile navigation system

With the development of GPS, GIS and mobile network communication technology, it has been becoming possible for mobile phone users to acquire the geographical information anytime and anywhere. This paper proposes a novel solution of embedded navigation system based on GPS/GIS that realizes some functions such as PDA data enquiry and parsing, terminal communication service, map application service, geographic information collection, embedded navigation electronic map etc. In this paper, we discuss the system topology architecture, technical scheme and the key realization technologies. At last, test results prove that the solution of embedded navigation system based on GPS/GIS is feasible and valid, and it can be installed in PDA, mobile phones and other portable information terminals.
