摘　　要：通过对多面函数和二次曲面模型的分析,提出了一种更高精度拟合高程的综合模型。结合实例,对比研究证实该方法的可行性,为大地高向正常高转换提供了一种参考思路。Through the model analysis of multi-faceted and quadratic function surface,we per present their features and usage in fitting GPS height.Based on different characteristics for fitting height anomaly,an integrated model is proposed,which can supply much better precision for fitting height.Finally,a case study indicates that fitting accuracy of the integrated model proposed is higher than that fitted by single.
