摘要
针对新疆部分区域用GPS2000网成果进行2000国家大地坐标系转换精度不高,通过利用测区周边IGS站,重新计算GPS控制网起算点,获得高精度三维空间直角坐标,再进行GPS控制网平差,获得其他各GPS点的2000国家大地坐标系成果。采用这种方法平差后,控制网精度较好,均能满足转换精度要求。
For some of the Xinjiang area with the results of GPS2000 network for the 2000 national geodetic coordinate system conver- sion accuracy is not high, by using the measured area surrounding the IGS station, recalculate the GPS control network starting point, to obtain high precision three -dimensional rectangular coordinate, then the GPS control network adjustment, won the 2000 national geodetic coordinate system results in every other point GPS. Using this method, after the adjustment, the control network accuracy, can meet the conversion accuracy requirements.
