摘要：

为解决部分现有的GPS（Global Positioning System）系统不提供地图支持，不能直观得到所处位置的地图信息等问题，设计了一种运用谷歌地球(GE： Google Earth)、基于89C51单片机的GPS手持系统。该系统以台湾Progin公司生产的SR-87模块作为核心GPS模块，通过无线射频芯片nRF24L01的Enhanced ShockBurst^TM专利协议的方式，将数据高速无缝传输到PC(Personal Computer)接收端。利用GE对外部设备良好的支持能力，将封装为国际标准的GPS协议NMEA（National Marine Electronics Association）数据导入软件内部，实现定位、导航等功能。测试结果表明，系统既可以独立显示经纬度、海拔、时间和卫星数等信息，又可以利用PC端软件GE获得地图信息。该系统可广泛应用于户外运动、野外科考及环境科学等领域。

Abstract:

Aiming at the problems that some of the current GPS（Global Positioning System） system could not provide map support and could not give map information about the location,based on 89C51 microcontroller, a GPS hand-holding system is designed and implemented by using GE(Google Earth).The system employs SR-87 module manufactured by Taiwan Progin corporation as its core GPS module. Through the Enhanced ShockBurst^TMpatent agreement of RF chip nRF24L01, hand\|holding transmitter seamlessly and efficiently sends data to PC(Personal Computer) receiver. Making use of the GE's ability to support external devices, PC receiver imports the packaged data in line with international standard GPS protocol NMEA(National Marine Electronics Association) into GE software, so as to achieve positioning, navigation and other functions. Results show that the system can display information of latitude, longitude, altitude, time, number of satellites,and obtain map information with the GE on PC side. This system is valued to field sports, expedition, the environmental sciences and other fieldwork\|related activities.

Key words: google earth, global positioning system(GPS) hand-holding system, nRF24L01 chip, national marine electronics association （NMEA） protocol
