| 摘 要： | 横向误差在贯通测量中至关重要。当地面控制采用GPS网时,其二维平差一般是先将WGS—84椭球(E_0)上的三维向量,经高斯投影公式转换成地方椭球(E_1)上的二维向量后再进行平差,得各GPS点的高斯平面坐标,最后由坐标平移和旋转公式得施工平面坐标。同时也分析了这一数据处理过程对贯通横向误差的影响。图1,表2,参10。

| Abstract: | Lateral error is essential in transfixion surveying. When the GPS network is adopted in the ground control network, the two-dimensional adjustment of GPS transforms the three-dimensional vectors of WGS-84 ellipse (E0) into two-dimensional vectors of local ellipse (E1) by utilizing the formula of Gauss projection in general, then the Gauss plane rectangular coordinates and the construction plane coordinates of all GPS points are acquired by adjustment and formula of coordinate parallel move & rotation. The influence on lateral error of transfixion in the data process are studied and analyzed in this paper. 1fig. ,2tabs. ,10refs. |
