hello,

i have an adis 16364 imu. i am trying to implementthe theory of kalman filter and i need the covariance of the accelerometer and the gyroscope.are this assumed to be gaussian noise?are these provided in the data sheet?i have read the data sheet and there are some error and noise values but i dont know if these values are related to covariance.

thanks a lot in advance!

This is definitely not something that is normally specified for our IMUs. I am not an expert of Extended Kalman Filters but I was under the impression that the co-variance terms were related to the noise, but also incorporated the conditions that could impact sensor variation in the estimation loops. For example, linear vibration would add to the co-variance of an accelerometer-based estimate. I can't promise anything but I will see what I can find out.
