A significant amount of future spacecrafts are spatially developed mechanical systems of variable configuration. Methods of their dynamics study can be highlighted as the part of dynamics of rigid bodies connected by various constraints moving under the influence of external forces. Need for the provision of such class of systems is due both to the fact that it is something inherent in common, which distinguishes them from all other formalisms to study dynamics and the fact that the results of the theory of motion can be applied to a variety of technical systems with a similar design features and areas of application. Natural and obvious representatives of such systems are large space structures designed for use in space. Models of their dynamics are usually represented by systems of differential equations of motion, and the numerical solution of these equations or analytical interpretation of possible solutions are understood as mathematical modeling. Features of such space structures and systems dynamics study are presented in the paper.
