Abstract

On the previous IACs we presented materials where we touched certain problems related to the analysis of conflicts of orbital bodies in the near-Earth space. In particular, there were presented certain "quick" methods of forecast of zones, dangerous of mechanical conflicts between orbital bodies, and methods of evaluation of the degree of danger of such zones. Also there were proposed a systemic approach to the analysis of the "state of conflicts" of a multitude of orbital bodies in the near-Earth space and conceptual solutions of building and use databases of orbital bodies.

In our paper we will present a survey of a problem of analysis of conflicts of a multitude of orbital bodies on a level of higher generalization. A classification of zones of conflicts has been worked out. For each type of zones methods, appropriate for "quick" forecast of their evolution and evaluation of the level of danger, were proposed and substantiated. The classification is based, first of all, on the stability of the zones over time. It has been suggested to divide them into stable (permanently existing or periodically appearing over a sufficiently long time interval) and unstable (appearing singularly or, though, with multiple appearance, having obviously aperiodic trends in their evolution). Zones stable and unstable in time are subdivided into several kinds depending on the peculiarities of their development. The additional classifying factors are altitudes, on which orbital bodies are positioned, and peculiarities of influence of systems of orbital corrections for spacecraft. The proposed classification is superimposed by the classification of zones by the degrees of their danger.

This classification and determination on its base of the methods of forecast of evolution of zones of mechanical conflicts are intended for implementation of methods of analysis of the "pollution" of the near-Earth space with conflict zones. Besides such a classification will be useful for development of databases on zones of mechanical conflicts in the near-Earth space.
