| Abstract: | In order to solve the geodetic height that GPS has measured converted into the normal height in the engineering project.This paper gave a method that GPS elevation fitting based on double cubic surface.It contrasted to curved surface and quadric surface of GPS elevation fitting by the measured data and calculation,the result showed that this method had higher precision than two others. |
