| Abstract: | The development of EGM2008 was reviewed in this article.And the Harbin local quasi geoid was calculated based on it.After that,some empirical analysis was done with the quasi geoid.Finally,a conclusion was drawn that it would be possible to achieve the goal of centimeter-level elevation measurement using GNSS with the calculated quasi geoid. |
