Hello All, I am using two wearable BNO055 sensors for inertial navigation. I am using 9DOF mode. At the end of my calibration the CA = 3, CG = 3, and CM = 3, however CS is unstable and fluctuates between 0-3. I have read other forums that say this instability of CS does not affect data quality, however, i have nearly every reason to believe that it is affecting our data quality, because we are seeing signifigant heading drift with our sensor. I have attached two photo of our inertial naviagation after walking in a square. From the piture you can see that the heading drifts substantially over time. The two photos are from the same data collection and "should" be identical. When i read the calibration values from the data collection, the CA, CG, and CM are all 3, but the CS ranges from 0-3 (and is 0 or 1) the majority of the time. Am i not using the correct firmware? Does anyone have any ideas how to deal with this problem? Thank you!
