FIELD: gravimeters for determining the acceleration of gravity.
SUBSTANCE: device contains a gravimetric sensor installed in a gyro platform for gyroscopic stabilization of the sensor, placed on a shock-absorbing device. The sensitivity axis of the gravimetric sensor is directed vertically and perpendicular to the plane of the gyroplatform. The center of rigidity of the elastic system of the shock-absorbing device coincides with the center of mass of the gyroplatform and the gravimetric sensor. The natural frequencies of the elastic system of the shock-absorbing device during translational movements in three orthogonal directions are equal.
EFFECT: reduced sensitivity of the gravimeter to external inertial accelerations, increased productivity of gravimetric survey.
