ABSTRACT:
A control method is disclosed which extends random drift improvement control to operation at high input rates. Traditional RDI control fails at high input rates due to the diminishing amplitude of the SBS; therefore, the control is lost. The present invention continuously samples the RDI control position and holds this RDI control position at its last previously recorded optimum value while the ring laser gyroscope is subjected to high input rates.
