Design of integrated positioning LBS mobile terminal based on C8051f340

This paper analyzed various components of integrated positioning LBS mobile terminal based on C8051F340, studied pseudo-range integrated positioning of GPS and GLONASS, deduced the combined observation equations and its solution, then used GPRS technology for transmission. Combining with those methods, we finally realized the integrated positioning LBS mobile terminal and tested it later. Experimental analysis shows that the accuracy of integrated positioning is superior to a single positioning system in bad observing conditions. Receiving and sending data of the service information are efficient carried out using GPRS. That such new technique apply to LBS system will enhance the service quality of LBS and promote the development of LBS.
