Abstract. A model of dynamics of the extended state vector of integrated system consisting of strapdown inertial navigation system and non-autonomous navigation system is proposed. An algorithm for estimation of notmeasured errors of accelerometers and gyroscopes and correction of their readouts in the further autonomous operation of the inertial navigation system is presented.
