METHOD AND APPARATUS FOR MEASURING GRAVITATIONAL ACCELERATION Russian patent published in 2012 - IPC G01V7/04

Abstract RU 2461027 C1

FIELD: physics.

SUBSTANCE: method and apparatus for measuring gravitational acceleration are based on determining angular velocity of rotation of a gyroscope and angular velocity of precession of the gyroscope. The angular velocity of rotation of the gyroscope is determined from the number of light reflections from the disc per unit time, and the angular velocity of precession of the gyroscope is determined from the number of precessions of light flux by the axis of the gyroscope. Gravitational acceleration is calculated using the formula where ω₁ is the angular velocity of rotation of the gyroscope, ω₂ is the angular velocity of precession of the gyroscope, R is the radius of the disc, l is the distance from the base of the axis to the centre of gravity of the gyroscope, which is in form of disc with light-reflecting segments.

EFFECT: high accuracy of measurements and wider field of use.
