ARM-LINUX平台下GPS信号的采集与处理研究
首发时间:2009-03-30
摘要:GPS信息的采集是导航定位系统的重要组成部分。本文先分析了GPS普遍采用的NMEA-0183通信协议;然后介绍了目标平台及交叉编译环境的建立;在此基础上实现了嵌入式ARM-LINUX平台下GPS的数据采集与处理,为导航定位系统或者GIS系统的应用奠定了基础。

Study On GPS Signal Acquisition and Processing Based On ARM-LINUX Platform
Abstract:The GPS data acquisition is the important element of navigation orientation system. Firstly, analyzing NMEA-0183 communication protocol used generally by GPS. Secondly, introducing goal platform and building cross compiling environment. Then the GPS data acquisition and processing system based on embedded ARM- LINUX platform has been realized, which plays an important role in navigation orientation system or GIS application.
Keywords: NMEA-0183 protocol, GPS, ARM-LINUX, cross compile multithreading programme
