Abstract
Computer simulation of the Fiber Optic Gyroscope (FOG) has not been well elucidated in existing studies. In this paper, we present a comprehensive method for FOG modelling. Different parameters affecting the performance of the FOG and its stability and sensitivity are discussed and the performance of the FOG with respect to vibration and shock is analyzed. The simulation results show that: (1) both the sensitivity and the stability of the FOG are improved by increasing both the length of the fiber coil and the gain of the electronics signal processing system, (2) the modeled FOG can have immunity to vibration with resistance against shock up to 90g [N].
