摘　　要：概述了导航型GPS接收机的工作原理和求解坐标转换参数的方法。在实际测量作业中,采取直接用导航型GPS测定已知公共点X、Y、Z值求解坐标转换参数的方法,从而降低了单点绝对定位的误差,达到了1∶10000比例尺地质填图定位测量的精度要求。The working principleof navigation-based GPS receiver and the parameter-calculating method for coordinate transformation are summarizedin this paper. In the practical surveying, the parameter -calculating method by determining X, Y, and Z value of known common point with navigation-based GPS is taken, so as to reduce error of utter location of single point, achieving the precision requirement of positioning survey of 1: 10000 geological mapping.
