Overview on modeling and compensation of FOG temperature drift

Based on the research results in recent years both at home and abroad,the paper introduces the mechanism of temperature drift of fiber optic gyroscope(FOG),summaries the modeling and compensation of temperature drift,and emphatically introduces the progress of software modeling and compensation.At present,the software modeling and compensation has been widely used,it can meet engineering targets for low-precision FOG,but the real-time online compensation has yet to be further raised for high-precision FOG.In the end,the paper points out the views about the design of temperature experiment and the compensation for FOG.
