A random walk is just integrated white noise. Therefore you need the
state-space equations of an integrator driven by white noise..

Hi
My final year project on Inertial navigation system using Gyro and
Acclerometer.
for filtering i calculate the bias,angular random walk and RRW variance
from Allan variance, But i dont know how to use it in Kalman filter
equation. Can anybody tell me How to write the matrix
x(k+1) = Ax(k)+ bu(k)+w(k)
y(k) = cx(k)+z(k)
i am measuring acceleration from that i have to calculate the velocity and
position
so what is w and z for this equation,is there is any relation between
allan variance coefficient nad w and z coefficient ?
i read many paper but i didn't anything about how to find the coefficient
of w and z using allan variance
please help me
regards
