Evaluation of geoid height derived by geopotential model and existing regional geoid model

摘要

A numerical analysis comparison has been made between derived geoid height from geopotential models and existing regional gravimetric and fitted geoid models. This study is part of an analysis of optimal global geopotential models to determine a seamless precise geoid model. A total of ten (10) recent global geopotential models were combined with satellite-only solutions in this study. Results from the statistical analysis show that EGM2008 and EIGEN-6C provide accurate information on deriving geoid heights for combined solutions, and GOCO01S is useful for satellite-only solutions.
