ABSTRACT:
The invention relates to a gravity measurement apparatus comprising a torsion balance bearing a test mass. The torsion balance has a predetermined center of mass and is rotatable around a predetermined rotation axis, wherein the torsion balance is asymmetric in such a way that the center of mass of the torsion balance is offset to the rotation axis of the torsion balance.
