| 摘 要： | GPS技术在测量领域已广泛应用,但GPS拟合高程精度制约了其在领域内的推广普及。选择不同的高程异常拟合模型,对GPS高程拟合精度非常重要。通过对驿城区城市控制网进行不同数学模型的GPS高程异常拟合,验证了选择合适的拟合模型及分布合理的高精度水准点,能够解算出高精度的GPS拟合高程,满足一般测量工程的需要。

| Abstract: | GPS technology has been widely used in the area of surveying,but its popularization is restricted by the GPS height fitting precision.Choosing different elevation fitting model is crucial to improving GPS elevation fitting accuracy.The carrying out of urban control network GPS elevation fitting under different mathematical model in Yicheng district proves that selecting proper fitting model and rationally distributed high accuracy benchmark can resolve high accuracy GPS fitting elevation and meet the requirement of common surveying projects. |
