Analysis on Application of EGM2008 on GPS Height Transformation in the Small Area
Zhang Guang-xing · Beijing Surveying and Mapping · 2013
Introduced to use EGM2008 model to calculate the elevation of the ground point exception principle.Pointed out that when an elevation known of GPS control network,How to apply EGM2008 through calculating height anomaly and prediction network the method of normal height.Use of jidong somewhere mountainous area and the beach two experimental plot data,to use the GPS height conversion method can achieve accuracy are analyzed,the conclusion is that in the small area can achieve fourth-order leveling precision.
