PROCESS OF CALIBRATION OF GYROSCOPIC MEASURING DEVICES OF ANGULAR VELOCITY Russian patent published in 2000 - IPC

FIELD: navigation. SUBSTANCE: inertial course vertical with gyroscopic measuring devices of angular velocity and accelerometers made fast to it is forced to rotate relative to three axes without use of gyroscopic stabilization. Signals proportional to position and integral components of horizontal components of apparent acceleration and of gyroscopic course are formed from output signals of gyroscopes, accelerometers and angle-data transmitters to plot calibration outline. Drift of gyroscopes, errors of scale coefficients, errors of asymmetry of scale coefficients and misalignment of sensitivity axes of gyroscopes integrated in single unit are determined. EFFECT: increased precision of calibration of gyroscopes at stage of initial preparation of inertial navigation system.
