摘　　要：本文以某市车载导航系统改造项目为依托,针对GPS接收机定时发送来的定位数据,利用计算机进行实时串行数据的接收和分离,实现动态显示。文中首先介绍了GPS目前的使用状况和遵循NMEA0183协议的GPS语句,提出了GPS串口通讯的一种新尝试,重点研究了如何自定义消息函数,把接收到的实时串行数据进行有效的分离。This article based on an amelioration project of navigation system of vehicles in some city explores how to receive and separate serial data to actualize dynamic display using computers and the position data regularly sent by GPS receiver.Starting with an introduction of the present use of GPS and GPS sentences conforming to NMEA0183 agreement the article proposes a new attempt of GPS serial communication placing an emphasis on how to self-define message function and separate the received serial data effectively.
