Redefinition of the international spheroid 1930
Tóm tắt
The equatorial value of normal gravity and the length of the semi-major axis of the currently used International spheroid 1930, appear to be mutually inconsistent in the light of the new astronomical values forKM and ω adopted by the International Union of Astronomy in 1964. This note accordingly suggests a new value for the length of its semi-major axis to remove this inconsistency.
