摘　　要：使用GPS25-LVS OEM板(接收机)接收卫星信号,通过串口异步通信把数据传送给89C51单片机,单片机通过并口控制LED显示,从而实现GPS准确授时.同时,介绍了GPSOEM板输出的数据形式,并采用NMEA-0183格式中最常用的"GPGGA"格式输出,由"GPGGA"数据输出格式可编写出相关的接收程序.The GPS25-LVS OEM board （receiver） is used to receive the satellite signal in this article. The data is transmitted to the 89C51 single-chip microcomputer through the serial port asynchronous communication and the LED display is controlled by the micr.ocontroller through the parallel ports. The output data format of GPS OEM board is introduced and it is used to output with the most frequently used ＂ $ GPGGA＂ format in NEMA-0183. Through ＂ $ GPGGA＂, the data output format, the relative receiving procedure can be programmed.
