VC6.0环境下GPS差分定位中串口通信的实现

The Realization of GPS Receiver’s Serial Communications in Difference Position under the Environment of VC6.0

文章从对GPS的差分技术的概述开始,继而以加拿大Novatel公司生产的OEM4-G2L板卡为例,介绍了NMEA0183协议及其中$GPGGA定位语句的格式,然后以详细的实例说明了基于VC6.0的计算机与GPS接收机在差分定位中的串口通信程序。

This article from to the GPS difference technology outline start, subsequently the OEM4-G2L board which produces by Canadian Novatel Corporation is an example, introduced the NMEA0183 agreement and its SGPGGA locate statement form, then the author showed by the detailed example based on the VC6.0 computer and the GPS receiver in difference position string mouth signal procedure.
