摘要
随着北斗二代系统的不断完善,为进一步拓展北斗应用领域,本文通过采用AM335X开发板、UM220北斗模块和嵌入式WIN CE系统,进行北斗应用开发并实现了北斗导航系统的基本功能。在以委托的方式完成串口数据读取的基础上,实现了NMEA数据的接收及处理,并进一步完成了经纬度、时间的显示,给出了可视星的星座图。经实际接收北斗卫星信号表明,定位数据显示准确实时,应用程序可稳定运行,对北斗二代系统终端的开发有一定的借鉴意义。
With the increasing improvement of the Beidou second generation system, in order to further expand the Beidou application field, this paper has achieved the basic functions of the Beidou navigation system by the use of AM335 X development board, UM220 Beidou module and the embedded CE WIN system. The receiving and processing of the NMEA data has been completed on the basis of reading the serial data by means of the delegate. Meantime, the latitude, the longitude and the time are further displayed. Finally, the constellation diagram of the visual star is given. Some conclusions can be obtained by receiving the Beidou satellite signal. The positioning data display of the system is accurate and in real-time. The application of the system can run stably for a long-term. Therefore, the research has certain reference significance to the development of the BD-2 terminal.
