BHI160B IMU Yaw drift issue

[Mukeshh]

Dear Team,

We are currently working with the BHI160B Bosch IMU sensor on an MAX Evaluation board. We have successfully read the Quaternions and calculated Roll-Pitch-Yaw (RPY) angles using 9DOF and 6DOF. 

However, we are encountering a Yaw drift issue with this IMU. Could an expert from Bosch provide assistance in resolving this technical challenge? or Could you provide the suggestions to overcome the Yaw drift issues in the BHI160B 

Additionally, we are interested in exploring other IMU sensors that do not suffer from Yaw drift issues. If there is an alternative sensor that performs better than the BHI160B, we would be keen to adopt it.

Your expert guidance would be greatly appreciated.

Best regards,
Mukesh

Hi Mukeshh,

Thank for your inquiry.
Before conducting the yaw drift test, it is necessary to ensure that the calibration outputs of ACC, gyro, and BSX fusion are 3 to ensure high accuracy of the algorithm's output data.
Also, what is your test? What is the error in testing the yaw drift? Do you have a detailed test report?
