Hello! I am a software engineer and currently we are doing a market analysis on the available MEMS-IMUs on the market. Currently I am evaluating BMI088 IMU and I am missing some technical parameters from the data sheet. I need to learn the Bias Instability term for accelerometer and gyroscope of the IMU and the misalignment term for the gyroscope. Could you please support me on this issue?
Thanks a lot for your help!

Thank you for your inquiry. BMI088 gyro bias instability is not specified in the datasheet. You can find it in the Flyer at https://www.bosch-sensortec.com/media/boschsensortec/downloads/product_flyer/bst-bmi088-fl000.pdf. It is less than 2 degree/hour.
BMI088 gyro has typical cross axis sensitivity of +/-1% in the datasheet. This corresponds to the misalignment error of +/-(atan(0.01)) = +/-0.57 degrees.
The BMI088 accel bias instability is less than 30ug. The typical accel alignment error is +/-0.5 degrees that is specified on page 9 of BMI088 datasheet at https://www.bosch-sensortec.com/media/boschsensortec/downloads/datasheets/bst-bmi088-ds001.pdf.
