运用谷歌地球的GPS手持系统的设计与开发

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n...

Design and Development of GPS Hand-Holding System Using Google Earth

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 ShockBurstTM patent 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.
