Hello, We are trying to use the BNO055 for accurate heading (±2 degrees). We want to use the device permanently mounted on a 3-meter mast that extends from a heavy hard iron vehicle. It is important for us to be able to calibrate the device once and store the offset values between power-ons. We intend to initially calibrate it in place on the mast by driving the vehicle around in figure eights. We intend to configure the device in fusion mode. Is there a specific mode that you would recommend for stable and accurate heading? Is there a way to disable auto calibration once the initial offsets are stored? Secondarily, will the sensitivity of the magnetometer be such that the heading would be significantly perturbed by passing vehicles or other metallic interferences? Finally, is there an alternative device such as the BNO080 that would be more appropriate for our application? Thank you.
