What methods are used to measure and correct MEMS accelerometer and MEMS gyroscope scale factors?

April 23, 2025

Usually, we fix the MEMS IMU to the turntable, and the accelerometer collects data using a 12-position stationary method. The gyroscope collects data by rotating forward and backward at specific speeds (such as 30 °/s, 60 °/s, etc.), and uses optimization algorithms to obtain the zero bias, scaling factor, and misalignment error matrix of the accelerometer and gyroscope.
