摘 要:在工程控制测量中,经常出现测区控制点稀少或无已知控制点的情形,基于全球连续运行基准站和IGS跟踪站,利用GAMIT进行长基线解算;再利用CosaGPS软件进行网平差计算和历元框架转换,精确求取待测点CGCS2000坐标;最后利用测区少量GPS/水准点和EGM2008模型进行似大地水准面精化,拟合得到待测点的正常高,为工程控制测量提供了一种行之有效的新思路。In engineering control survey, the control points in the survey area are scarce or there are no known control points. In this paper, based on the global continuous operation reference stations and IGS tracking stations, we used GAMIT to calculate long baseline, and used CosaGPS software to calculate the network adjustment and convert the epoch frame. Then, we obtained the CGCS2000 coordinates of measured points accurately. Finally, we used a small number of GPS/leveling points in the survey area and EGM2008 model to refine the quasi-geoid surface and fit the normal height of measured point. This study can provide an effective new idea for engineering control survey.
