摘要
介绍了全球定位系统(GPS)的基本工作原理,讨论了GPS-OEM板的组成和特点,分析了NMEA-0183语句的数据格式及信息组成,并结合硬件特点研究了MCS-51单片机与GPS-OEM板的串行通信问题,讨论了GPS应用系统的软硬件配置问题,并给出了单片机读取导航数据的有关汇编程序源代码。
The basic principle of Global Positioning System(GPS) and the construction of GPS-OEM board are introduced. The data format and information construction of NMEA-0183 standard is analysed. The serial communication between MCS-51 and GPS-OEM board based on the hardware construction is studied, and then the software and hardware configurations are discussed. Finally the communication program for reading the navigation message is provided.
