The results of the modeling of joint work  of the control system with  the aircraft inertial navigation system are represented in this article .For  improving the accuracy of the control the results of  calibration of inertial sensors with are used. It is shown that the developed method of calibration of inertial sensors with middle accuracy   allow to improve the quality of inertial measuring unit and use it in automatically control system of aircraft.
