Sins / Gps Integrated Navigation Missiles

In the paper, in view of the characteristic of shell/missile' s control and guide, SINS/GPS integrated navigation system is applied to shell/missile.Firstly, The whole scheme of shell/missile integrated navigation system is introduced. Including the selection of aerodynamic force layout, the mode of coming into being control power, mode of navigation, the control system' s structure of shell etc. The paper introduce the principle of SINS(Strap-down Inertial Guidance System), and complete procedure arranging and simulating. Secondly, In term of characteristic which shell shall get great force of impact when it is launched, The paper designs the initial alignment methods for the SINS working on this condition. In addition, the paper discusses the principle of integrated navigation system and the integrated mode, and designs kalman filter of integrated system. Finely, the paper designs software and hardware of data acquisition system(DAS), which can collect SINS parameter and receiving GPS information. To meet system' s demand, the paper designs 6-channels simultaneous sampling scheme. To reduce the room of circuit and improve the stability, the highly integrated level, predominant, special IC is used in this system.
