摘要
介绍一种基于单片机的GPS信息处理系统。以ATMEL公司的单片机AT89C2051作为核心控制器件,LCD和键盘作为人机界面,通过串行口接收GPS接收机输出的NMEA-0183标准格式定位数据,选择GPGLL和GPZDA两种数据格式获取地理位置信息和时间信息。经时差修正等适当的数据处理后,将获得的地理位置信息和时间信息显示于用户数据终端。
A single chip computer based design of GPS information processing system is introduced. This system employs ATMEL＇s AT89C2051 as core controller, LCD and keyboard as Human Machine Interface（HMI）, receives NMEA - 0183 standard formed navigating data,among which GPGLL and GPZDA are selected to acquire geological information and timing information respectively. Finally the acquired geological information and timing information are displayed on the data terminal after proper data processing such as time difference correction.
