    Hi community,

    Could you please provide any recommendations or suggestions for a digital compass that would be used in automotive applications?

    Hi Serhat,

    Bosch Sensortec’s sensor fusion software BSX is a complete 9-axis fusion solution which combines the measurements from 3-axis gyroscope, 3-axis geomagnetic sensor and a 3-axis accelerometer to provide a robust absolute orientation vector. The sensor fusion software BSX provides orientation information in form of quaternion or Euler angles.
    The algorithm fuses the sensor raw data from 3-axis accelerometer, 3-axis geomagnetic sensor and 3-axis gyroscope in an intelligent way to improve each sensor’s output. This includes algorithms for offset calibration of each sensor, monitoring of the calibration status and Kalman filter fusion to provide distortion-free and refined orientation vectors. Since Bosch Sensortec 9-axis fusion software is developed together with the sensor hardware, optimized performance in terms of dynamics and immunity to distortion effects is achieved.
    For more detailed information about BSX sensor fusion for smart sensor systems, you can see application note https://www.bosch-sensortec.com/media/boschsensortec/downloads/application_notes_1/bst-bhi260_bhi360...

    The complete BSX sensor fusion software is integrated with the smart sensors BHI260AP, BHI360 and BNO055.
    For new applications, we recommend using BHI360+BMM350 to support the compass.

    Additionally, Bosch Sensortec’s product & BSX solution are consumer grade.
