Abstract
A computer-implemented method for operating a gyroscope sensor system. The method includes: receiving sensor values of a gyroscope sensor of the gyroscope sensor system; ascertaining an angular rate of the gyroscope sensor by applying a Kalman filter to the sensor values of the gyroscope sensor; and ascertaining, by a calibration algorithm, a gyroscope offset of the gyroscope sensor based on the angular rate of the gyroscope sensor ascertained by the Kalman filter. A gyroscope sensor system is also described.
