THE bias instability of BNO055

[huiyuanai]

I want to use the IMU simulation model in Matlab to simulate my IMU attitude estimation algorithm. The data sheet only gives the noise density of gyroscopes and accelerometers, and lacks the bias instabilities of gyroscopes and accelerometers. I'd also like to know the rate  random walk (RRW)of the gyroscope if I can.

Hi,

Thanks for your inquiry.

The gyroscope inside BNO055 is the same as the one inside BMI088. According to BMI088 Flyer at https://www.bosch-sensortec.com/media/boschsensortec/downloads/product_flyer/bst-bmi088-fl000.pdf the gyro bias instability is less than 2 degrees/hour. We don't have other parameters for BNO055 accel bias instability and gyro RRW. You may use a few BNO055 to do your own Allan Variance test and characterization.

Thanks.
