FIELD: instrument engineering.
SUBSTANCE: invention relates to instrument making and can be used in designing angular velocity sensors (gyroscopic sensors) used as sources of primary measurements of inertial orientation and navigation systems. Method of compensating for the systematic component of drift of the zero signal of the angular velocity sensor involves formation of a compensating signal from the zero signal and its subsequent use to correct the measured signal of the sensor. At that formation of compensating signal is performed at each sensor start by means of polynomial approximation of zero signal by least squares method at specified time interval selected from conditions of application and calculating by the coefficients of the approximating polynomial the predicted values of the compensating signal for the required time moments of the correction of the measured signal of the sensor.
EFFECT: high accuracy characteristics of sensors.
