摘要
达州市独立坐标系GNSS网测量中,联测6个IGS参考站点,按B级网的要求解算出了4个控制点在CGCS2000椭球下的独立坐标,并将此作为GNSS控制网的起算数据对剩余23个GNSS控制点进行了平差处理,经过实例分析,该方法可以满足独立坐标系建立要求。
The six IGS reference stations were jointly surveyed when the independent coordinate system GNSS was measured at Dazhou. The independent coordinate of the 4 control points based on the CGCS2000 ellipsoid were worked out and as the initial data of the GNSS control network to adjust the balancing of the rest of 23 GNSS control points. With the analysis of the projects,this method can meet the requirement of the establishment of independent coordinate system.
