摘要

GPS导出的椭球体高度，在已知的正交高度点，用于确定沙特阿拉伯的大地水准面。采用最小二乘配置法求思想最优大地面。得到的大地水准面可以用于许多有益的应用。例如，根据GPS测量结果直接确定正测高度，而不需要调平。

A proposed algorithm for geoid determination in Saudi Arabia using GPS measurements

GPS derived ellipsoidal heights, at points of known orthometric heights, were used for the determination of the geoid in Saudi Arabia. The technique of least-squares collocation is applied for the derivation of the thought optimal geoidal surface. The derived geoid can then be used for a multitude of beneficial applications. For instance, the determination of orthometric heights, directly without levelling, from GPS measurements.
