摘要
采用协方差拟合推估模型拟合GPS高程异常,在介绍协方差拟合推估模型的基础上,讨论了几种确定协方差函数的模型,并结合数据对各种拟合方法进行了比较分析。
It presents the theory of the covariance function prediction can be used in the fitting of abnormal height. On the basis of introducing the model of the covariance function prediction, it discusses the models of the covariance function in detail and analyses the results of the fitting methods.
