| 摘 要： | 为了研究稳健估计法在GPS高程拟合中的抗差能力，通过模拟在已知点中分别加入0．05m、0．1m、0．2m和0．3m的粗差以及在两个已知点中加入粗差，并采用二次曲面拟合法、BP神经网络模型和基于Huber法定权的稳健估计法进行对比。计算结果表明，稳健估计法应用于GPS高程拟合具有较好的抗差能力。

| Abstract: | In order to study the error resistance capability of the robust estimation method in GPS height fitting, through the simulation of gross errors in 0.05m,0.1m,0.2m and 0.3m were added in the known points and in the two known points with error,then compare application of the two curved surface fitting,BP neural network model and robust estimation method based on Huber given the right.The results show that,the robust estimation method is applied to GPS elevation fitting has good robust capability. |
