In the dither ring laser gyro (DRLG) strapdown inertial navigation system (SINS), gyro outputs are often pre-filtered to eliminate the dither modulated, but the influence of the filtered data on the attitude algorithm Is often ignored. It is found that the conventional coning algorithms can not work to high accuracy for the filtered gyro outputs which have a shaped frequency. So the coning algorithm must be optimized to match the frequency response of the dither demodulation filter. The… CONTINUE READING
