摘　　要：介绍了GPS定位中有关坐标参考框架的一些重要概念,对坐标参考框架的一致性问题和采用GPS协议地球坐标系(ITRF或WGS-84)作为变形基准的特点及其适用性进行了对比分析,提出了采用ITRF作为变形分析基准时的坐标参考框架的转换与统一方法。Some important concepts on the coordinate reference frames in GPS Positioning are introduced. The consistency issues of the coordinate reference frames are analyzed and the characteristics and applicability which using the GPS conventional terrestrial coordinate system （ITRF or WGS-84） as deformation reference are compared. The conversion and unified method of the coordinate reference frame using ITRF as deformation analysis reference is proposed.
