The invention relates to means for gravimetric measurements on movable basis. Aviation gravimetric system for measurement of abnormalities of acceleration of gravity includes system for determination of navigation parameters and height measuring device that are connected to the first and second inputs of airborne computer (AC) and gyroscopic gravimeter. Gravimeter includes two three-stage gyroscopes rotors of which are arranged as such that rotate in opposite directions, and centers of masses of those are shifted by same distance to one side along axes of rotation. On the axes of the outer frame of three-stage gyroscopes the first and the second indicators of angle are placed, and at axles of the inner frames the third and the fourth indicators of angle are placed. To the AC block for algorithmic compensation of errors of measurement of acceleration of gravity is included. To the first, second, third and fourth inputs of the block outputs of the first, second, third and fourth indicators of angle, respective, are connected. The invention provides increase of accuracy of measurements of abnormalities of acceleration of gravity. |
