摘　　要：针对目前自主式车载导航终端在地图数据动态更新和实时交通信息接收方面的不足,基于网络与自主式导航相结合的思想,该文采用基于GPRS的组合式车载导航服务终端的设计方案,阐述S3C44B0X模块、GPS模块、GPRS模块以及电源等主要模块的组成结构和工作原理。对终端进行调试,对接收的数据进行优化。该硬件设计方案结合软件设计将有利于实现地图与道路数据的动态更新和基于实时交通信息的动态导航。Considering the deficiency of the presently autonomous vehicle navigation terminal on dynamic updating of map data and reception of real-time traffic information, this paper presents the design options, which is based on the thought of combining the network with the autonomous navigation. It is accomplished by the combo vehicle navigation terminal which is based on GPRS. This paper introduces the structure and principle of S3C44BOX, GPS, General Packet Radio Service（GPRS）, electrical source and other major modules, debugs the terminal and optimized the data received by GPS. The design options of hardware, while combining with software, is conducive to achieve the dynamic updating of map data, and the dynamic navigation which is based on the real-time traffic information.
