In this paper ,the dynamic error vector equation of the initial alignment in an inertial navigation system and the observability problem of the dynamic error vector are analysed firstly,then a design of Kalman filter is presented. Simulation results show that the proposed Kalman filter algorithm is available to the initial alignment in an inertial navigation system.
