Three-coordinate gravimeter with exhibition of axis sensitivity based on digital videoimages

Abstract

The paper presents a new design of a three-axis gravimeter of aviation gravimetric system, which provides compensation for errors caused by influence of mobile base vertical accelerations and in the result of measurement of full gravity acceleration vector. Angle of inclination of a mark that is applied to a gravimeter body and coincides with vertical sensitive axis direction is determined by linear approximation in digital video images. These data are used to point sensitive axes and improve gravimeter accuracy.
