Geodesy Practical Work: Reduction of Astronomical Observations at the North Pole

Authors: Abdelmajid Ben Hadj Salem
Comments: 7 Pages. In French

During astronomical observations, we refer to the instantaneous North Pole. The observations had to be corrected to transfer them to the conventional pole.

Theory of Surfaces: Application To The Equipotential Surfaces of The Normal Field of Gravity

Authors: Abdelmajid Ben Hadj Salem
Comments: 6 Pages. In French

Recently, in an article, we reviewed some models of equipotential surfaces of the normal field of gravity relative to the Earth. In this note, we will apply the important theorems of surface theory to the surface obtained from the second model whose normal gravitational field is given by:$$ U= frac{Gm}{r}+frac{1}{2}omega^2left(x^2+y^2ight) $$

Note About The Equipotential Surface of The Normal Gravity Field U=U_0

Authors: Abdelmajid Ben Hadj Salem
Comments: 12 Pages. In French

The object of this note is to present the equation of the surface which defines the equipotential field of gravity $U=U_0$ for certain models of the normal potential of gravity $U$.
