1.	Which method uses a turntable in RLG to reduce lock-in errors?(a) Intensity control(b) Rate biasing(c) Using mechanical dither(d) Random rate fixing
Answer» Right answer is (b) Rate biasing Explanation: The method of rate biasing employs a turntable that applies a constant rotation to the gyro. An angular encoder measures the relative angle between the instrument and its base.
