| 摘要: |
| 简单介绍了GPS系统及GPS接收机的通信协议，给出了接收机和计算机之间的电平转换硬件电路，并着重讨论了VC＋＋6．0环境下两者进行通信的2种实现方案：一种是API通信函数法，一种是MSComm控件法。最后给出了GPS用户数据提取的一般方法。这种通信方式和数据提取方法同样适合其他GPSOEM产品。 |

| Abstract: |
| By analysing the GPS system and the communication protocols,the electric conversion circuit of GPS receiver to computer is introduced,and two realization schemes based on VC are discussed: one is the method of API,the other is MSComm control.The general way of data separation is given.The communication modes and the means of data separation can be also used to other products of GPS OEM. |
| Key words: GPS receiver NMEA - 0183 data format serial communication data separation |
