Abstract :
This thesis studies the bias drift compensation of ring laser gyro (RLG) against external environment, especially thermal effects. Bias drift is linearly proportional to temperature, and temperature gradient. So thermal effects can be removed from gyro in terms of temperature, temperature gradient. This study also shows analytically the temperature change rate and temperature gradient has same effect on the gyro.
