Gyroscopic gravimeter with digital data processing about acceleration of gravity is considered in a paper. The result of measurement in gyroscopic gravimeter contains errors. An influence gravimeter inertial absolute acceleration and other disturbing influences cause the errors of measurements. These of acceleration arise, for example, by work gravimeter onboard the plane in structure of air gravimetric system. The structural scheme and construction of gyroscopic gravimeter is proposed in a paper for multiple precision. This construction is providing immediate measurements of acceleration of gravity. The possibility to fulfil digital processing and filtration of measuring information in a computing device of gravimeter is appeared also. The possibility of digital data processing is considered in view of a two-dimensional character of an array of measuring information.
