摘要
以ARM9微处理器S3C2440A为硬件平台核心,WindowsCE嵌入式操作系统为软件平台,构建了微型化、便携的差分GPS导航定位系统。在Visual Studio2008开发环境中采用MFC编程技术,编写导航定位软件,通过RS232串口读取差分GPS接收设备输出的$GPRMC信息,解析后用于显示和导航参数计算。系统在开阔场地进行了实验,运行正常并得到了精度良好的导航定位结果,具有重要的实用价值。
By using S3C2440A microprocessor as hardware platform core and WindowsCE as software platform,a miniature and portable differential GPS navigation and position system was constructed.Navigation and position software was developed in the Visual Studio 2008 based on the MFC technology.SGPRMC data was transmitted from the Differential GPS receiving devices to microprocessor through the RS232 serial port, after analysis which was used to display and navigation parameter was calculated.At last,the system worked outdoor for test,it did well and the test results were good navigation and positioning accuracy, it had important practical value.
