Abstract: A method includes simulating operation of a fiber optic gyroscope during a digital simulation. The simulation includes performing an iterative loop that includes simulating an intensity of light from a fiber coil of the fiber optic gyroscope and simulating operation of one or more control loops within the fiber optic gyroscope using the simulated intensity of the light.
