移去恢复法的深入探讨与混合拟合模型的建模研究

摘要

高精度GPS高程转换是GPS理论与应用研究的热点问题，其研究对GPS测量成果的实际应用至关重要。本文从探求移去恢复法的本质出发，以二次曲面拟合模型和多面函数拟合模型为基础，建立混合拟合模型，并以实验证明该方法有效可行。%GPS height transformation with high-precision is the hot issues in its theory and applications, its research essential for the practical application in the results of GPS measurements. This article to explore the nature of removed to restore, based with hardy function interpolation and quadratic surface fitting model, establish the mixed-fitting model, experiments proved that the method is effective and feasible.
