| Abstract: | It is suggested that it would be worthwhile to determine the absolute value of the geopotential on the geopotential surface
which corresponds to mean sea level. This number would replace the earth’s semi-major axis as the parameter which fixes the
earth’s size; but slight variations in the parameter might be employed to study the dynamics of the sea.
Fixing this number involves knowing the geopotential for a point on the orbit of a satellite whose true gravitational potential
is also known. |
