IT-TECHNOLOGIES IN THE PROBLEMS OF IMPROVING EFFICIENCY WITH THE ASSOCIATED START AND SEPARATION OF THE MICRO SATELLITE ON-BOARD SPACE APPARATUS

Abstract

Recently, the study of the near and far space with the help of small spacecraft has become more important. In this regard, we can definitely talk about the whole industry of small space technology, the problems of its creation, application, launch and operation. Today we have a large arsenal of carrier rockets of various classes, numerous conversion rocket technologies has been accumulated, allowing, directly or indirectly, to ensure not only the delivery of small space technology to working orbits, but also to perform control and other functions for basic spacecraft of various purposes. This paper addresses the problem of the relative motion of small spacecraft, taking into account their layout on the launch platform and separation parameters. As a solution, an algorithm is proposed for finding the optimal layout of devices on the platform and modeling their separation and subsequent movement. The choice of perturbing factors that are used in the simulation of orbital motion is substantiated. The results of the layout and graphics of the relative position of the launch platform and the small spacecraft, the relative position of the two separated vehicles at a given time interval are given. The modeling of the movement of the separated apparatus near the international space station is presented.
