Calibration Method and Experiment Study on Low Cost MEMS Gyroscope

The price of MEMS gyroscope is cheap,but the sensor is characterized by large errors. Therefore,in order to reduce systematic errors,we need to test and calibrate the performance parameters of the sensor to establish accurate output mathematical model. This paper presented the MEMS gyroscope dynamic and rocking experiments and verified the selected three axis digital MEMS gyroscope has good dynamic speed tracking and test performance. And then according to the output of the MEMS gyro mathematical model,it designed the scheme of calibration experimental of the three axis digital gyro. The experimental data shows that the scheme is correct and effective.
