摘要
对地球重力场模型和GPS高程测量数据应用EGM2008模型进行GPS高程拟合转换,并给出工程算例进行分析。计算表明,应用EGM2008模型转换后的GPS高程数据精度达2 cm,可满足大多数起伏较大的山区高程测量需要。
The paper carries out GPS height simulation conversion of earth gravity field model and GPS height measurement data by applying EGM2008 model, and makes an analysis by integrating with engineering examples. The calculation results show that ： the GPS height data accura- cy is up to 2 cm after EGM2008 model conversion, which can meet the undulating mountainous height t need
