利用地壳运动观测网络工程的基准站为框架点,解算了七个ZZCORS站和九个GPS等级控制点的CGCS2000地心坐标,并对计算结果的精度进行了分析。
We implement geodetic conjunction within the coverage area of zhengzhou continuously operating reference system(ZZCORS),and baseline solution and network adjustment for observation data.5 base stations of crustal movement observation network of china are used to build the framework of Zhengzhou area,and Geocentric coordinate of 7 stations of ZZCORS and 9 control points is resolved under CGCS2000.The precision of results is analysed.
