Acquiring knowledge in the field of navigation guidance and control of missiles with the possibility of application in the fields of research and development, design, production, marketing, operational use and analysis of modern guided missiles. Mastering the methodology of calculating the dynamic characteristics of guided missiles. Acquisition of knowledge in the field of autopilots, different autopilot algorithms, as well as their synthesis. Introduction to different types and algorithms of control laws and their synthesis. Mastering inertial navigation as well as getting acquainted with algorithms for coupling inertial navigation with other types of navigation.

The student acquires general knowledge in the field of analyzing and synthesizing a GNC system of guided missiles that enable participation and communication in work teams involved in the development of guided missiles. The student is trained for independent work in the fields of navigation algorithms as well as the selection of the necessary inertial seasons either for the navigation systems or for the needs of the missile guidance and control system. The student masters various algorithms and techniques from the calibration of inertial sensors and elements of the guidance and control system to synthesis of guidance algorithms and autopilots, algorithms for missiles stabilization. With the use of modern software environments MATLAB and SIMULINK, the student is trained to apply and analyse algorithms in this field.

Kinematic Euler equation and algorithms of solving (Euler's angles, quaternions, Hamilton's parameters, Rodriges's theorem). Gyroscopes and accelerometers. Calibration of inertial units, testing and error correction. The basics of the global positioning system. Aided navigation systems. Introduction to the theory of guidance and control of the missiles (the basic principles of guidance and control). Analysis of dynamic characteristics of missiles and calculation of aerodynamic transfer functions. Requirements and methods of designing autopilots. Analyses and syntheses of proportional navigation, the command to LOS guidance and different approaches for trajectory correction and trajectory guidance.
