The purpose of the work is to determine the dynamic characteristics of the orbital grouping of space objects, taking into account the mobility of attachment points on the base platform. Research methods: mathematical and computer modeling, system design, space flight mechanics. The analysis of the state of development of small and ultra-small spacecraft was carried out, it was found that the share of small spacecraft launched into orbit has almost doubled in the last decade. The analysis of the state of development of space inflatable systems is carried out, it is shown that this class of systems is sufficiently developed and thus the technical feasibility of creation of space inflatable platforms is confirmed. A mathematical model for estimating the design parameters of a space inflatable platform with payload has been developed, which includes three main modules: module of orbital translational and angular motion, module for determining thermodynamic and gas-dynamic parameters of an inflatable space platform and module for calculating variable inertia tensor. while moving in orbit. Test simulations of the orbital and angular motion of the space inflatable platform with a payload were performed. The efficiency of the model of orbital perturbed motion of the space inflatable platform is shown taking into account the influence of perturbations. The peculiarity of the dependence of the variable inertia tensor on the temperature during the movement on the solar and shadow sides of the orbit is established. In the first approximation, the controllability of a nonlinear system with a variable inertia tensor is estimated. The results obtained at this stage will be used in the study of the dynamics of the grouping of space objects, taking into account the mobility of the attachment points on the base shell.
