A METHOD FOR DETERMINING THE DRIFT OF A GYROSTABILIZED PLATFORM CAUSED BY TORSIONAL VIBRATIONS OF THE BASE OF THE DEVICE Russian patent published in 2023 - IPC G01C21/18 

FIELD: instrumentation.

SUBSTANCE: invention relates to the instrumentation and can be used in the creation of inertial control systems to determine the parameters of controlled mobile objects. The character of the claimed invention is as follows. The precession angles of gyroscopes are measured in the instrument coordinate system associated with the platform. Then, the values of the moments of disturbing forces around the stabilization axes are determined, causing the appearance of precession and stabilization angles. Next, the stabilization angles corresponding to the moments of perturbation of the platform around the stabilization axes are determined. The moments of nonlinear disturbances around the precession axes are determined. As a result, the drift under the impact of nonlinear disturbances is determined.

EFFECT: increasing of the accuracy of determining the navigation parameters of the object by compensating for the drift of the gyrostabilized platform.
