What's the system noise matrix of ADIS16448 in Kalman filter?

Hello everyone,

I'm using ADIS16448 to realize navigation with GPS. For my data fusion system with Kalman filter, my IMU device realizes mainly the "Prediction" step of Kalman filter, so I need to know the system noise matrix Q from IMU, which mainly contains the PSDs of the accelerometer and gyro noise, and the bias variation PSDs. However, I cannot find the exact data from the specification of ADIS16448. So I want your help to determine the parameter that I need.

Thank you very much!
