Paper Abstract

The temperature characteristic of components used in open-loop fiber-optic gyroscope (FOG) were studied independently and their relevant temperature models of thermal induced error were obtained A digital compensation method, in which a simple phase sensitive detection electric circuit and a microprocessor were adopted and the error compensation was realized with digital processing technology, was proposed. Experimental study showed that the bias drift of FOG tested was reduced abut 80% in the temperature range of 20 degrees Celsius - 55 degrees Celsius after compensation.
