ABSTRACT:
In order to eliminate gyro errors of electrically caged, two-axis gyros, which have a pick-off (52,54) and a torquer (46,48) on each input axis, and each pick-off (52,54) arranged on one input axis energizes the torquer (48,46) on the other input axis, a first measurement is made with a first direction of rotation of the gyro rotor (42). Subsequently, for a second measurement, the direction of rotation of the gyro rotor (42) is reversed and, at the same time, the polarity of the signals from the pick-offs (52,54) is inverted. A measuring value is formed from the gyro signals obtained with both of these measurements.
