浅析新疆CORS与原有点CGCS2000坐标差异与处理方法

Differences Between XJCORS and Original Control Points in CGCS2000 Coordinate System and Its Processing Method

新疆CORS于2016年8月开始试运行,1 a来为各行各业提供了方便快捷高精度的位置和导航服务,但在应用过程中发现坐标框架与已有控制点的CGCS2000成果存在一定差异,分析了该问题产生的原因,介绍了CORS框架坐标的建立方法以及原有控制点坐标的来源;并针对二者成果差异提出了相应的处理方法。

XJCORS began trial operation in August 2016.It had provided a convenient and efficient high-precision location and navigation services for all walks of life.But there were some differences about control point results between XJCORS and CGCS2000 coordinate system.According to this,we analyzed the reasons of the differences,and introduced the establishment method of XJCORS’framework coordinates,as well as the sources of the original control point coordinates.And then,aiming at the differences between those two results,we put forward a corresponding processing method which could provide a certain reference for the domestic same trade or occupation of CORS.
