    Allan Deviation (or Velocity/Angle Random Walk and Bias Stability) for BMI085 and BMI088

    Hi,

    I am planning to use either BMI085 or BMI088 in an integrated navigation system for the usage in a quadrocopter. Therefore I would like to ask kindly for some Allan Deviation Curves for both sensors and its six dimensions (acceleration and gyroscope). If these curves are not published, I am in particular looking for the Velocity Random Walk (VRW), the Angle Random Walk (ARW) and the Bias Stability together with its timespan for which it is defined. I guess the VRW and the ARW are given in the datasheets as "Noise density", but I can hardly find informations for the Bias Stability to calibrate both my simulation model of the sensor and my Unscented Kalman Filter.

    Thank you in advance for your answers!

    Best regards,

    Marco

    Hi,

    These data requires NDA (non-disclosure agreement). You could contact local sales or FAE from bosch-sensortec-sales-contact .

    BMI088 Flyer show bias bellow:

    The automotive-proven gyroscope of the BMI088 has an unmatched bias stability of less than 2°/h and a low temperature coefficient of offset (TCO) below 15 mdps/K.

    Best regards.
