Goal: development of new and improved of existing methods for the analysis of nonlinear mechanical processes in the structural elements of aviation, rocket and space technology and ensuring the accuracy of motion control systems Methods of investigation: methods of mechanics and applied mathematics, such as finite element method, mathematical modeling, in particular, finite difference methods; methods of navigation theory, such as correction of INS state vector, increase of accuracy of determination of initial values, use of external satellite measurements. The creep constitutive equation based on the recovery effect at cyclic loading was obtained and justified, an analysis of deformation of the shell structure was performed by use of it. New continuous solid's rotation models have been developed. The approach to increasing the accuracy of navigation systems due to the schemes of correction of the state vector in conditions of redundancy of information in the system is developed. Mathematical and algorithmic support as well as software architecture of integrated inertial satellite navigation systems on micro-sensors are developed.
