Hi
I'm working on a GPS/INS model.
Now I developped the mecanization equations for the INS.
I have a kalman filter which estimate the error state (position error with respect to north and east).
it takes as an input the diffrence between GPS and INS and gives its estimation .
I have developped a gauss-markov process which very similar to sensor noise (after applying wavlet).
Now, I don't know what can I do during the GPS outage ?
Because the mesaures are not available during this periode; I can't use Kalman filter.
Documentation that I have, doesn't say clearly what to do during GPS outage.
