Abstract
In order to study the relation between the scale factor and temperature of small low cost ring laser gyroscopes (RLG) deeply, and improve its performance without increasing cost on hardware, theoretical analysis and experiments were carried out. Data of scale factor both in given temperature and in slowly changing temperature were obtained. Those experimental data conformed to the theoretical data approximately. The equation between scale factor and temperature was built and thus the scale factor error caused by temperature was apparently reduced.
