摘要
系统硬件以AT89C55微处理器为核心,采用AG132和GPS25lvsOEM接收板二次开发、液晶显示器、RS-232电缆及其它外围器件开发设计的;应用Keil C51实现了GPS信息的提取、显示等。经实验证明:该通用型GPS接收系统能够较好地适应不同型号的GPS,正确接收和解译NMEA-0183语句。
The core of this system＇s hardware is AT89C55 MCU. The system was developed by using the AG132 and GPS251vsOEM receiving board. The hardware system also included LCD, RS--232 cable, and the other outer devices. The system＇s software used Keil C51 to realize picking up and displaying GPS signal, and the basic control. By the experiment, the universal receiving system can be adapted to different models of GPS, receive and decipher NMEA--0183 statement correctly.
