基于脚踝导航的追踪器设计研究
摘 要
中国北斗卫星导航系统作为中国独立发展、自主运行的全球卫星导航系统，是国家正在建设的重要空间信息基础设施，可广泛用于经济社会的各个领域。
随着空间信息技术的发展，卫星导航系统的运用日益深入。同时，计算机硬件技术与通讯技术的进步，对导航脚踝式追踪器的信息处理能力、便携性以及交互性提出了更高的要求。当前，市面上的主流导航定位脚踝式追踪器大多基于GPS系统，对他国依赖程度很高；而基于北斗导航系统的脚踝式追踪器由于体积大、能耗高、价格贵等影响，推广应用并不理想。针对这一问题，本文提出了在嵌入式操作系统基础上，利用北斗导航系统实现定位，设计了一种移动导航定位脚踝式追踪器。该移动导航脚踝式追踪器由通讯模块、定位模块、地图显示、地图搜索、电子地图以及系统维护模块组成，可实现定位、地图查询、路径选择等多种功能。

Based on the ankle navigation tracker design research
Abstract
China’s beidou satellite navigation system as the development of Chinese independent, autonomous operation of the global satellite navigation system, is the national important spatial information infrastructure is under construction, which can be widely used in various fields of economic and social.With the development of space information technology, the use of satellite navigation system is becoming more and more deeply.At the same time, the progress of computer hardware technology and communication technology, for navigation ankle tracker, portability, and interactive information processing capability, higher requirements are put forward.On market at present, the mainstream of the navigation and positioning ankle type tracker based on GPS system, mostly to other countries rely heavily.Ankle type tracker based on beidou navigation system such as large volume, high energy consumption, the price is expensive, application is not ideal.In order to solve this problem, this paper put forward on the basis of embedded operating system, using the beidou navigation system to realize positioning, designed a mobile navigation positioning ankle tracker.The mobile navigation ankle type tracker by the communication module, position module, display, map search, electronic maps, and system maintenance module, which can realize positioning, map query, path selection and other functions.
