A Method for Fiber Optic Gyroscope Temperature Drift Compensation Using Correlations between the Readings of the Gyroscope and Several Temperature Sensors

摘要

Abstract The paper discusses the problem of temperature drift compensation in a fiber-optic gyroscope, using a number of temperature sensors distributed along the gyroscope coil. An algorithm is proposed for processing the sensors’ data in the form of weighted sum of temperature values and its derivative. The results of the proposed algorithm comparison with an algorithm that uses averaged readings of sensors are presented. It is shown that the proposed algorithm increases the compensation accuracy up to 50.
