摘　　要：:AVLN系统是空间定位技术和地图有机集成的产物。GPS、GIS和现代通讯技术的集成直接影响着AVLN系统的技术构成。目前 ,AVLN系统推广应用的主要困难是缺乏数字地图和实时交通信息。导航数据的生产、交换、销售和保密处理对AVLN系统具有重要意义。定位数据处理、数字地图显示、分析查询以及数字通讯为一体的导航软件研制具有现实意义。The Automatic Vehicle Location and Navigation (AVLN) system is the integrate result of the space location and map.The composition of the GPS,GIS and modern communication technology influences the technical constitution of the AVLN system directly.Now,the main difficulty in spreading and applying AVLN is the lack of the digital map and timely traffic information.The production,exchange,selling and secrecy disposal of the Navigation Datum is very important to AVLN.The study of the navigation Software,which is the integration of the disposal of the location datum、the display、analysis and query of the digital map and digital communication does have a realistic meaning.
