DETERMINATION OF STATIONARY WAVE ORIENTATION ANGLE IN SOLID-STATE WAVE GYRO Russian patent published in 2014 - IPC G01C25/00 

FIELD: instrument making.

SUBSTANCE: invention relates to precision instrumentation and can be used in production of solid-state wave gyros and navigation systems built thereon Proposed method consists in that gyro is arranged on rotary table bed so that gyro input axis is aligned with that of table rotation and directed vertically Two reference magnitudes of angular velocity are set for said bed to measure gyro readings in stationary wave orientation angular range of ±90° and to define the difference in tube width in gyro readings change in preset angular range of its orientation at different angular velocities of the bed Correction factors for generated magnitudes of synphase and quadrature components of sine and cosine channels of gyro angle transducer are selected to minimise said difference in gyro readings in tube width In operating mode, angle of stationary wave orientation relative to resonator is defined with the help of analytical expression, its parameters being corrected during preliminary operation.

EFFECT: higher precision.
