摘要
为提高GPS高程异常拟合精度并减少已知点的数量,以提高流域规划高程控制测量工作效率,文中利用重力场模型高程拟合残差建立区域较高精度的线状似大地水准面拟合模型。该方法在联测较少高等级水准的情况下,区域高程拟合精度满足流域规划控制测量对高程精度的要求。
In order to further improve the aberrant fitting accuracy of GPS height,meanwhile to reduce the number of known points and to increase the measurement efficiency of river basin planning height,a regional linear quasi-geoid fitting model with higher accuracy was established using height fitting residual of gravity field model.Under the circumstance of joint measurement with less high-level by this method,the regional height fitting accuracy met the height accuracy requirements of controlling measurement in r...
