METHOD AND DEVICE FOR MEASUREMENT OF GRAVITY ACCELERATION Russian patent published in 2013 - IPC G01P15/14 G01V7/00 

FIELD: measurement equipment.

SUBSTANCE: proposed method involves determination of angular rotation speed of a spinner and angular precession speed of the spinner in straight and reverse positions of the spinner. A disk with through holes in the form of a segment, which is put on an axis, is used as a spinner. Angular rotation speed of the spinner is determined as per the number of intersections of light flux with the disk segments per unit of time. Angular precession speed of the spinner is determined as per the number of intersections of light flux with the spinner axis. Gravity acceleration is calculated by formula $$g=\frac{R^2({\omega }_1{\omega }_2+{\omega }_3{\omega }_4)}{2L},$$ where ω₁ - angular rotation speed of the spinner and ω₂ - angular precession speed of the spinner in straight position, and ω₃ - angular rotation speed of the spinner and ω₄ - angular precession speed of the spinner in reverse position, L - spinner axis length, R - disk radius.

EFFECT: improving determination accuracy of gravity acceleration.
