Anti error Fitting of GPS Height

Yue Dongjie Huang Teng(College of Civil Engineering, HoHai Univ., Nanjing 210098)  
The common fitting method of GPS height, the existing problems and resolving methods are discussed. The Anti error fitting of GPS height is a good method, which, according to the adjusted information, adjusts the weight of observations(the known points) and makes the weight with gross error of observations become smaller and smaller, even zero as a result, the influence on the result reduces greatly. The method can raise the precision of height interpolation.Finally the effectiveness is testified through a case study.
