In the article the algorithmic method of increase of accuracy of linear accelerometers is considered. In the gyroscopic accelerometer the angle of deviation of a sensing element consists of a constant and variable making. The constant making is proportional to acceleration, which is considered constant on an interval of one measurement. Variable making is determined by precessions of a sensing element. In conditions of presence of correlated distortion of determined and random character it is necessary with high accuracy to define values of a constant making. This problem is solved in the article because of method of a maximum probability. The realization of algorithm of identification of an angular rule of a sensing element because of artificial neural network application is offered. This network contains a delay line and three adaptive linear neurons. The procedures of training and adaptation of a network provide additional error reduction in non-stationary and unfavorable conditions. The obtained outcomes can be used for a construction of high-precision navigational and gravimetric systems.

The most perspective gravimeters which work in structure of aviation gravimetrical system is gyroscopic. Nevertheless doublerings in comparison with singlerings dynamically adjusted gyroscopes, have advantages, most powerful of which: higher accuracy and speed, small dimensions, high sensivity. In work it is received the equations of movement new dynamically adjusted gravimeter which will enable to investigate it(him) further, to make mathematical modelling, to define static and dynamic errors.

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.
