Conversion of GPS Height by the Method of Neural Networks Considering of EGM96

LIU Shuai,ZHU Jian-jun,ZHAO Ling-li(School of Info-Physics and Geomatics Engineering,Central South University,Changsha 410083,China)  
The EGM96 model and the method of neural networks used for transforming GPS height are introduced briefly in this paper.The processes take full advantages of the two methods and are divided into three steps: Firstly,the height abnormal values on the known points are removed by EGM96.Secondly,the remained values are calculated by the method of neural networks.Finally,resume the height values.A few practicable conclusions are received from the research.
