Vehicle Navigation Embedded Terminal Design Based on Beidou Positioning Technology

Design ideas of beidou navigation terminal based on S5PV210 processor with GPRS wireless communication technology is proposed. The paper mainly introduces vehicle navigation terminal hardware structure, and the main chip characteristics and its peripheral schematic design of microprocessor module, power supply module circuit, the design of Memory and the Nand Flash, Audio module, the BD/GPS dual-mode module, SIM900A GPRS module was analyzed emphatically. Test results show that the position precision of the BD/GPS module in this design meet the requirements of vehicle navigation, and the stability of the GPRS module to a large number of data communication is very good, which can realize the real-time exchange of data control center and navigation terminal. Thus it overcome the deficiency that the traditional navigation cannot realize the real-time data communication with control center.
