MEMS gyroscope has broad application in objects posture monitoring and navigation control as low-cost inertial measurement unit.A 3-axis digital gyroscope calibration experiment is designed based on mathematical model of MEMS 3-axis digital gyroscope.The processing method of scale factor

installation error coefficient

and value of zero bias of MEMS 3-axis digital gyroscope in mathernatical model is introduced.Theoretical analysis and experimental results show that this calibration method is simple in principle

easy to implement and has high calibration precision.The solving matrix after calibration can provide more accurate measurement data for the following attitude resolve and the navigation control

while the process of calibration and data processing methods have certain reference value for MEMS 3-axis digital gyroscope calibration.
