The three-axis MEMS gyroscope measures the angular rate of the carrier, the three-axis MEMS accelerometer measures the linear acceleration of the carrier, and the product carries out the zero position, scale factor, non-quadrature error and acceleration-related terms of the whole temperature parameter compensation, which can maintain high measurement accuracy for a long time, and its independent structure integrates high-performance MEMS gyroscope and MEMS accelerometer, and the selected gyroscope and accelerometer represent the leading level of MEMS process inertial devices.
