摘要
自从美国GPS投入使用以来,卫星定位系统以其全天候、实时、动态和连续等优势在军事、交通、水利和授时等多个领域得到广泛应用。为了便于卫星定位系统与其他设备进行信息交互,国内外发布了大量的应用标准,与海洋测绘相关的主要有NMEA0183.RTCM SC104和RINEX。介绍NMEA机构及NMEA0183协议发展,分析该协议的通用格式,并解析常用的GGA、VTG和ZDA数据格式。
Since GPS was put into use in the 1980s,satellite positioning systems have been widely used in military,transportation,water conservancy and timing because of its great advantage in all一day,real-time,high一dynamic and continuous output.In order to communicate between satellite positioning devices and other device such as computer,lots of standards have been developed such as NMEA 0183,RTCM SC 104 and RINEX which have been widely used in hydrographic survey.This paper first introduces the institution of NMEA and the development of NMEA 0183 standard,then analyses the generic format,GGA,VTG and ZDA.This will offer technical detail for applications in hydrographic survey.
