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 Mj

Therefore you need the state-space equations of an integrator driven by white noise..

why worry sir.. your kind of thesis is already done at chalmers..when i was there in chalmers http://db.s2.chalmers.se/download/masters/master_049_2003.pdf thanks particlereddy
