摘　　要：结合二次曲面法拟合GNSS高程的原理,探讨该方法在区域似大地水准面拟合求解正常高的可行性,进而以Visual Basic 6.0为平台,设计实现高程拟合系统,最后利用工程实例对高程拟合系统进行检验,测区拟合后内外符合精度分别为5.6 mm和17.5 mm,达到四等水准精度要求,验证了该拟合系统的可靠性。系统简单方便,适用于类似工程的数据处理。Based on the theory of GNSS height fitting by quadratic surface method, the paper discusses the feasibility of its application in calculating and fitting regional quasigeoid. And then an elevation fitting system is built based on Visual Basic 6.0. And the GNSS elevation fitting system is tested by engineering projects. The results show the in- ternal and external precision are 5.6mm and 17.5mm respectively which demands accuracy requirements of the na- tional fourth order leveling and verifies the system reliability. Finally, this system is simple and applicable in simi- lar engineering data processing.
