A piezo-gravimeter relates to measuring engineering and can be used for carrying out gravimetric measurements on movable base in geodesy, geology, inertial systems of navigation. The piezo-gravimeter comprises a sensitive element that measures a set of acceleration of force of gravity and interferences caused by displacement of movable base of gravimeter in space, and a device for calculation of output signal of gravimeter that corresponds to acceleration of force of gravity. Sensitive element is arranged as a piezo-pack. Frequency of intrinsic vibrations of the piezo-pack is equal to the highest frequency of gravitational accelerations that can be measured at background of interferences. Output of sensitive element is connected to the input of the device for calculation of output signal of gravimeter. The invention makes it possible to increase accuracy and reliability of measurements. |
