不同地形条件下多种GPS高程拟合模型的适应性研究

摘要

A combination model based on the remove-recovery principle was proposed.The model was established according to structure characteristics of each model,and analysis results of adaptability of the model under different terrain conditions of various engineering examples.The model is suitable to different terrain conditions.%通过对几种常见模型的结构进行分析,并根据各模型的结构特点,采用“移去-恢复法”原理建立组合模型.结合工程实例,对不同地形情况下各模型的适应性进行分析,提出了适合于不同地形条件的高程异常拟合模型的选取方案.
