Bagmut I. Improvement of the correction methods in the aircraft integrated navigation system

Object of research: controlled process evaluation parameters in the integrated navigation system. Research objective: increase the accuracy of the integrated inertial-satellite navigation systems by developing and improving methods methods of correction of current measurements of motion parameters of the aircraft. Methods of research: methods of automatic control theory, methods of theory of inertial navigation and navigation systems, state space methods, methods of linear algebra and differential equations, methods of synthesis of statistically optimal control systems, methods of mathematical and simulation modeling. Theoretical and practical results are to improve the accuracy of operation of the integrated navigation system by applying the improved method of correcting inertial measurements. Using introduced in the thesis measures of observability can accelerate the process of analysis and synthesis of dynamic systems of high dimension. Scientific novelty of the work lies in the further development of methods for correction of integrated navigation systems by detailed models of the measurement errors of inertial sensors, which reduced the errors of navigation and spatial parameters of a moving object, as well as in the results obtained analyzing the observability of the main types of instrumental errors of the inertial unit with various types of aircraft apparatus that allowed us to determine conditions for their efficient estimation. Implementation extent: scientific and industrial enterprise "Khartron-Arcos"(city Kharkov), Closed Joint Stock Company "Lasex" (city Dolhoprudnyy, Russia), NTU "KhPI". Sphere of appliance: development and modernization of navigation and control systems of moving objects.
