探讨了岭估计方法在GPS高程拟合中的应用，并给出了岭估计中确定岭参数k值的一种新方法——方差扩大因子法。通过某地区GPS水准网数据进行实验验证，结果表明，与传统多项式曲面拟合模型比较，岭估计方法具有拟合精度高、适用复杂的地形等特点。

In polynomial surface fitting process, ill-conditioning problems of normal equation may lead to unreliable least squares estimation results. The application of ridge estimation in GPS Height fitting with polynomial surface is studied in this paper. A new method is developed in determining ridge parameter k of variance inflation factor. It is concluded through GPS Height experiments in certain areas that it is more precise than traditional polynomial surface fitting modes and can be well applied in complex terrains.
