利用GPS精化区域似大地水准面
REFINING LOCAL QUASI GEOID WITH GPS
【摘要】 基于原有似大地水准面,在区域设计一些具有高精度的GPS大地高和水准高的公共点,采用数学拟合方法可得该区域似大地水准面的精化模型。由精化后的似大地水准面可得到区域内任一GPS测点的水准高程,从而代替五等水准测量和三角高程测量。
【Abstract】 By designing some points with high precision GPS-height and leveling-height in the studied region,the refined model of quasi geoid based on the existent one can be obtained with the method of mathematical simulation.From the refined quasi geoid,the leveling-height of any GPS point in the region can be obtained instead of fifth order leveling and triangulated height surveying.
