| Abstract: | 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. |
