摘　　要：提出一种基于高程拟合的数据处理方法,充分利用GPS高精度的三维观测,实现了将三维空间坐标转换为二维平面坐标。通过与传统椭球投影的结果对比,两者平均点位偏差为0.6 mm,结果表明了方法的正确性。由于无需椭球投影,这为平面坐标的数据处理提供了一种简单可行的方法。GPS and leveling were used respectively for planar and elevation measurement of the primary control network in particle accelerator facility.To get the planar coordinates,a new method based on height fitting was proposed to process the spatial coordinates observed by GPS,which achieved coordinate transformation from 3D to 2D by taking full advantage of the high accuracy of GPS.Compared with the traditional el-lipse projection method,the average point deviation is only 0.6mm.iff demonstrates the correctness of the proposed method.It provides an easy and feasible way to for data processing becauseellipse projection is not needed.
