【摘要】 分析了车辆导航系统的历史和现状,提出下一代导航系统为基于网络的导航信息服务系统-Navigation Telematics System(NTS)。定义NTS为一种通过无线网络为汽车和个人等,提供基于实时交通信息的动态车辆导航服务为主的信息服务系统。采用垂直方向上划分功能层,水平方向上划分功能模块的原则设计了NTS的系统结构,该结构具有独立于平台、可扩展等特点。分析了其中不同功能层的组成,详细论述了NTS的核心功能。更多还原

【Abstract】 Analyzing the history and actuality of the vehicle navigation system,we think that the development trend of the system is network based navigation information service system—Navigation Telematics System(NTS).NTS is defined as traffic information based dynamic navigation information service system for vehicle and person through wireless network.A principle of dividing function levels in vertical direction and function modules in horizontal direction is used to design NTS system architecture,which has the characteristics of independent to platform and extensibility.Then the paper introduces and describes the components of different function levels and core functions in detail.更多还原
