摘　　要：探讨了基于LBS的嵌入式数字城市空间管治信息系统 (DCSGS)导航系统总体结构模型。设计实现了GPS自主导航系统的导航区域设置、航线设置、轨迹跟踪、航路标点等功能模块。介绍了开发平台与导航数据结构。详细给出了PDA系统与GPS导航仪通讯解决方案、轨迹跟踪推算定位算法和嵌入式GIS集成等关键技术。This paper discusses the total structure of a navigating system for embedded information systems of the space governance in digital city based on LBS. The function-modules including area setting, navigating-line setting, track-tail, lane marking-point, etc, are designed and implemented for GPS independence-navigation system. The flat-stage of a system development and the navigation data- structure are introduced at one time. The author gives detailedly in PDA resolving-scheme in communication with GPS, the arithmetic of a track-tail pointing, and the key-technology of the integration at embedded GIS atc.
