Design & Implementation Of Vehicle GPS Navigation System

In this paper,a Vehicle GPS Navigation System is introduced and implemented. The system includes a main control console, a GPS subsystem and a GSM/GPRS subsystem. The main control console takes charge of communicating with users and controlling subsystems. The GPS subsystem is used for receiving and disposing GPS data. The GSM/GPRS subsystem is used for communicating with the Monitoring and Dispatching center or others. The work process is that the GPS subsystem receives GPS data from GPS satellites, disposes and sends them to the main control console; the main control console matches GPS position data with digital map and displays on the LCD of the system. If the system wants to communicate with the Monitoring and Dispatching center or user wants to communicate with others, the GSM/GPRS subsystem can be used.The main control console consists of ARM microprocessor, Linux operating system and Minigui. The key technologies include GPS, GSM/GPRS, GIS, Embedded Technology, Linux, ARM, and Data Processing Technology.The main functions of the system are implemented, including browsing digital map, navigation and positioning, communicating, and connecting internet. The results are very well.
