摘要
二次曲面转换GPS高程,求取转换参数所列的方程,方程系数矩阵由已知点的坐标组成,本文提出利用归一化的方法优化坐标系数矩阵,求取坐标参数。计算结果和精度优于利用坐标中心化、平均法进行处理的算法。
During conversion of GPS Height, the equation is built to calculate parameters of the conversion. Coordinates of known points equations constitute the coefficient matrix. The paper improved the coefficient matrix by normalized method, then calculated co- ordinates parameters. Calculated results were more accurate than those of coordinate-centric and average methods.
