摘要
介绍了GPS高程拟合原理,结合工程实例,运用平面拟合和二次曲面拟合两种GPS高程拟合方法,并对这两种拟合方法进行了分析比较,指出在不同地区应采用不同的拟合方法,从而提高拟合精度。
Principle of GPS evaluation fitting is introduced.Combined with practical work two GPS evaluation fitting methods： plane fitting and quadratic curve fitting are introduced.Comparison is also made for those two fitting methods.Author points out that according to various situations different fitting method should be selected in order to increase fitting accuracy.
