Micro-machined (MEMS) gyroscope is widely used in various control situations. How to improve the precision of MEMS gyroscope is a problem worthy to study. Based on the sensor array technology, the gyros array structure and auxiliary circuit module are designed. The hardware structure of the virtual gyro is tested and analyzed. The accurate output of gyro is obtained through the temperature compensation and filtering fusion algorithm. According to the study, virtual gyroscope technology can improve the precision of MEMS gyroscope to a certain extent and reduce the cost of high precision gyroscope. The application value of virtual gyro technology is verified.
