The purpose of the study is to develop mathematical software of control system for spatial and angular motion of the service spacecraft (SSC) at the final stage of reproaching and docking with uncooperative spacecraft (USC). USCs are called spacecrafts with inoperative (or missing) navigation and attitude control systems, as well as objects of space debris. The three-dimensional graphical model of the USC, given in its body-fixed coordinate system, is assumed to be known. Research methods of the study are filtering and processing digital images, computer graphics, spacecraft dynamics, methods of ellipsoidal estimation of nonlinear dynamical systems, methods of solving nonlinear systems, methods of graph theory and learning. The obtained results: robust methods of ellipsoidal estimation of the state of nonlinear dynamical systems in the conditions of structural-parametric perturbations and action of uncontrolled perturbations; methods and algorithms for controlling the translational-rotational motion of the SSC for approaching the USC, which may be in a state of uncontrolled rotational motion, and hovering at a given distance from the USC with the specified parameters of relative attitude. Branches of application: enterprises of the space industry of Ukraine, research and educational institutions of the NAS and the Ministry of Education and Science of Ukraine.
