Abstract The vertical deviation of a local height datum from the geoid is essential and fundamental for the transformation of regional datums and the unification of the global height datum. The value of the gravity potential of Qingdao Dagang tidal station is acquired by using 936 GPS leveling point data and EGM2008 geopotential model, which is 62 636 852.85±0.07 m 2/s 2 , in turn ,a vertical deviation of 0.32 m of Chinese height datum from the geoid is obtained.
Key words ：
EGM2008 model
geoid
height datum
gravity potential
vertical deviation
