摘要
主要介绍ＧＰＳ２０接收机和ＩＢＭ－ＰＣ机组成的数据采集系统。分析了接收机的定位误差情况，讨论了输出定位信息的相关性问题。
The system of a real time data acquisition which consists of GPS20 receiver and microcomputer is described. The position error of the GPS receiver is analyzed and the output autocorrelation of the GPS receiver is discussed.Finally, the dynamic displaying technique of the output signal and relative application function are also given.
