Abstract
A ring laser gyroscope or other motion sensor is dithered at a first rate if a global positioning signal is available and/or when alignment is not being performed, and is dithered at a second rate if a global positioning signal is not available and/or when alignment is being performed. The second rate is greater than the first rate.
