ISM330DHCX vs ISM330BX vs LSM6DSV32X

[phly]

We need ~50k 6-axis IMUs for an application that will experience > 2000dps yaw rate and highly dynamic motion. 

The spec sheets for the ISM330BX and LSM6DSV32X seem to not paint a complete picture regarding the angular zero-rate at different G_FS angular rate measurement range.

We're looking for an ST engineer to make a recommendation for the highest-quality IMU with respect to angular drift and accuracy while in highly dynamic motion. We are interested in IMUs with on-board sensor fusion. 

Other questions:
The ISM330BX seems to be better than the ISM330DHCX in several dimensions, but appears to use a different accelerometer that is not strictly better than what is found in the ISM330DHCX. Is this correct?

Is there an IMU that can be classified as "strictly the best" IMU under highly dynamic motion & vibration for mobile vehicle and robotics applications?

Hi @phly ,

Welcome to ST Community!

The angular zero rate is not reported at different FS because it is tested only in characterization and thus not guaranteed in production. If you need this information I suggest you to contact our online support here that can share with you some data.

For dynamic motion & vibration for mobile vehicle and robotics applications have you already looked at ASM330LHH?
