摘要
本文对NMEA-0183协议的基本格式进行了介绍,并分析了NMEA-0183格式数据的解析原理,在此基础上,对基于Linux系统的NMEA-0183格式数据实时提取与处理方法进行了研究,编写了与其相关的端口通信程序和数据解析处理程序,最终实现了Linux系统下的NMEA-0183原始数据提取、解析处理和传输过程,并通过GNSS接收机板卡进行了实验验证。
This paper introduces the basic format of NMEA-0183 protocol, and analyzes its data analysis principle. On this foundation, the real-time extracting and processing method of NMEA-0183 format data has been studied based on Linux system and the relevant port communication program, data analysis and process program have been designed. Finally, the NMEA-0183 original dam＇s extract, alysis and transmit process based on linux system have been achieved, and it has been proved by an experimental verification through GNSS receiver board.
