基于ARM的嵌入式GPS通讯 摘 要 关键词Linux；ARM Based on the ARM embedded GPS communications Abstract As the global positioning system in the aerospace, aviation, marine, ocean processes, geodesy, land navigation, and extensive use of its military broad application prospects, making the GPS positioning and navigation system into the field of competing domestic and foreign object of study. This paper presents a structured ARM-based processors, open source embedded linux system and the open map data to build an embedded GPS positioning and navigation system map design. Based on GPS satellite positioning technology, the dynamic can be a moving target position (longitude and latitude), time, status and other information transmitted in real time via wireless communication link to the monitoring center, which is displayed on the electronic map of the trajectory of the mobile terminal movement, And the terminal position, velocity, direction of movement, alarm information of interest to users to monitor and query parameters. This paper presents an embedded ARM-based auto-positioning system, with a small footprint, high performance, high reliability and configurable features, and can be successfully ported to a variety of hardware and operating system platforms. Building the system hardware and software platform, based on the GPS map navigation by studying the critical theory and technology, including the positioning data protocol analysis, system digital map to select, coordinate conversion, vector map visualization and roaming, zooming and other operations, design and Development of the upper GPS, map software modules, enabling GPS map navigation function.
