基于改进的Kriging法区域似大地水准面精化
Area Quasi-Geoid Refine Based on Improved Kriging Method
摘要
Abstract
When Kriging method is used in GPS elevation fitting, its accuracy is above zero because of the model errors and common point errors. An improved Kriging method is introduced to refine area quasi-geoid by correcting the fitting residual of the known point. Analysis of GPS elevation fitting accuracy through the Kriging method and the improved Kriging method by the measured data shows that the improved Kriging method has high accuracy than Kriging method, and can reduce the model errors and common point errors effectively.关键词
