METHOD FOR COMPENSATING CROSS ERRORS IN MEASURING CHANNELS OF DYNAMICALLY TUNED GYROSCOPE Russian patent published in 2023 - IPC G01C19/02 

FIELD: instrumentation.

SUBSTANCE: method for reducing cross-errors in the output information of the angular rate sensors (ARS) based on the dynamically tuned gyroscope (DTG), caused by the impact of angular accelerations, is characterized by the fact that the angular velocities are measured along the first and second channels of the ARS based on the DTG and fed to the first inputs of the adders, the angular acceleration of the second channel is fed to the second input of the adder of the first channel. Angular acceleration of the first channel is fed to the second input of the adder of the second channel, and the angular accelerations are obtained by differentiating the measured angular velocities of the first and the second channels and scaled to the scale of the angular velocities using the corresponding cross-link coefficients. Further, in each adder, the angular rate of the corresponding ARS channel is compensated with the involvement of the angular acceleration of the adjacent ARS channel resulting in compensated angular rates of each channel of the ARS based on the DTG.

EFFECT: increased accuracy of the ARS based on the DTG.
