Abstract
A dither stripper for laser gyro dither including a digital microcomputer which controls the stripping of the dither signal from the inertial navigation signal of the laser gyro. The dither stripper schedules internal A/D conversions using an A/D conversion arbitration scheme as well as calculates the expected system sample clock. Accurate dither stripping is achieved using a phase locked loop feedback system which compensates for real time changes in dither pickoff components while incorporating an accurate gain control mechanism.
