Abstract
GPS technology has been widely used and developed into a real 3D measurement tools.However,GPS technology elevation precision is still the GPS positioning key technology to research and solve problems.Using GPS technology values of the elevation is the ground point in WGS84 coordinate system height,presently our country's practical vertical system USES is the normal.This paper analyzes the height calculation with GPS,discusses the methods and results.Based on the experiments,this method calculates the elevation abnormal value and solves the problem of elevation transformation.关键词
