A direct digital dither drive for a laser gyro dither motor including a digital microcomputer which controls the dithering of a laser gyro to prevent lock in of the laser beams. The digital drive senses a dither position and schedules internal A/D conversions using an A/D conversion arbitration scheme. The period frequency and location of the minimum and maximum drive are determined using the microcontroller. Accurate dither drive is accomplished using a digital analog feedback system which compensates for real time changes in dither pickoff and dither drive components.
