METHOD FOR MEASUREMENT OF GRAVITATION CONSTANT Russian patent published in 2009 - IPC G01V7/00 

FIELD: physics, measurement.

SUBSTANCE: invention is related to metrology and may be used in specification of fundamental physical constant - gravitation constant. According to invention, attractive mass is aligned in two or more positions, in all positions they measure periods, amplitudes of torsion balance oscillations and distance increment from initial point, making system of equations, distances are calculated between interacting masses and gravitation constant. Invention specific feature consists in the fact that during fixation of attractive bodies in two positions, masses are displaced and fixed by two units perpendicular to line of torsion balance equilibrium cyclically in both directions, varying it for the opposite one after measurements at every of two positions, moreover, the first position is placed on line of balance equilibrium in close proximity to rocker weight, and the second one is selected based on produced maximum of torsion oscillations period.

EFFECT: reduction of gravitation constant measurements error by weakening of destabilizing factors related to microseisms, unbalanced flows of diluted gas and presence of operator for selection of the following position.
