METHOD AND DEVICE FOR COMPENSATING ZERO SHIFT ERROR OF CORIOLIS GYROSCOPE Russian patent published in 2007 - IPC G01C19/56

Abstract RU 2310164 C2

FIELD: navigation.

SUBSTANCE: method comprises modulating frequency of oscillations to be red, demodulating output signal from the circuit for control of speed of rotation synchronously with the modulating frequency of oscillations to be red for generating the additional signal that is a measure of the zero shift error, and generating compensation signal. The compensation signal is supplied to the input of the circuit for control of the speed of rotation. The compensation signal is generated so that the value of the additional signal is as low as possible.

EFFECT: enhanced precision.
