摘　　要：介绍一种采用GPRS(GeneralPacketRadioServic)技术作为GPS车载卫星定位系统的无线数据传输链路的方法,有效地解决了因为GSM(GlobalSystemforMobileCommunications)技术的传输速率限制,所以无法实时传送车辆定位信息的问题。阐述了GPRS-GPS车载卫星定位系统的组成结构和工作原理,并介绍了承载GPRS的ARM(AdvancedRISCMachines)嵌入式硬件平台的设计和软件TCP/IP以及PPP等网络协议栈的建立。基于该方案设计的车载终端设备经过实际测验,达到预期的设计效果。This paper discussed a method, using GPRS technology, which can solve the problem of communication speed limit in GSM -GPS Positioning of Vehicles.It can transmit the positioning information of automobile in Real-Tune through GPRS wireless data transmission link.The architecture and working theory of the GPRS-GPS Positioning of Vehicles is introduced in details, focusing on design of ARM embedded hardware system and development of software stacks such as TCP/IP, PPP, etc, which are the main parts of this solution.The onboard device based on the GPRS technology was tested, with satisfied results.
