Predictive methods and models are used to identify the state of satellite communication channels. However, they evaluate their condition only at a qualitative level, which does not allow fine-tuning the characteristics and parameters of satellite channels. Such models and methods cannot provide reliable identification of the States of satellite communication channels and quickly determine changes in the distribution laws of random variables associated with the appearance of small-scale inhomogeneities in the case of dynamic changes in the ionospheric layer, which is typical for rapid fading of GPS/GLONASS signals.

The Caspian issues are considered in various aspects by numerous domestic and foreign researchers. The region is gaining particular importance in connection with the signing of the Convention on the Legal Status of the Caspian Sea (dated 12.08.2018), which formed new geopolitical and geo-economic realities and a new vector of integration development on the Eurasian continent. More and more attention is paid to the subject of the spatial development of the Great Caspian in the East-West and North-South coordinate systems. The US policy in the Middle East, including sanctions pressure on Iran, is aimed at destabilizing the political and economic situation in the region, and also provides for restraining the progressive development of the largest Asian economies in the world. This paper considers some conceptual approaches to the formation of a concept and a multidimensional model of the Great Caspian Sea, as a geopolitical center of regional and global interests, dynamically changing the spatial conjugation of multi-vector forces of international influence based on institutional transformations. An approach to creating a new geopolitical space within the framework of the "Great Eurasian Triangle RIC" with the base of the "Great Caspian" triangle pulling together the leading players in world politics and encircling the Eurasian continent with the most important transport routes is considered. The formation of "multidimensional spaces" - triangles, as the most stable political-economic and physical-geographical international structures (formations), represent the spatial realities of the Great Caspian Sea, as a new geopolitical dimension - a megaregion.

The issues of interdisciplinary integration of research methods of political processes are of particular interest from both theoretical and practical points of view. Application of methods of system analysis, decision theory, mathematical and simulation modeling to the study of political, socio-economic systems is a non-trivial task that allows you to identify patterns and trends in the development of systems with behavior, gain experience in forecasting and comparative analysis of research results. The article presents the results of the research, the subject of which is to determine the conditions for the applicability of the game-theoretic approach to the study of political processes. The article is devoted to the game-theoretic approach in the study of political processes. The authors define the possibilities that open up the application of game theory to the analysis of complex systems with behavior. According to the authors, the relevance of the research topic is determined by the insufficient attention of the scientific community to the tools that representatives of exact Sciences are ready to provide to political scientists and sociologists. The current state of formal modeling in political science is at the stage of initial definition of the subject of research and formation of the concept.

The article is devoted to identifying the accentuation of the confessional factor in the socio-political process of the Russian Federation against the background of its stabilization and stagnation vectors. There are trends in including the confessional factor in the official discourse of state leaders, the position of the head of the Russian state in relation to religion, faith, and the role of religious institutions. Political programs and discourse of political leaders in relation to the role, goals and tasks of religious institutions are analyzed.

The title of this work is derived from the term "geopolitical cosmology" by which we mean the ability of geopolitics to design abstract schemes that clearly explain the essence of their developed geopolitical strategy. This is a kind of test of the logical strength of specific geopolitical doctrines. If they pass this test, they have a future. Otherwise, we are faced with a stillborn doctrine. Analysis of most of these strategies indicates that they were most often intended to intimidate the enemy with their boldness and originality, and other than psychological impact had no practical value. The problem considered in this paper concerns the now widely discussed topic of changing geopolitical poles in the system of world leadership. We are talking about a new geopolitical configuration of Eurasia, where two triangles are built - the Western one (Germany, France, Great Britain) and the Eastern one (Iran, India, China). Both of them are located at different poles of the Russian border and have a certain influence on it. In turn, Russia itself becomes the main geopolitical participant in these international relations, which it exerts a specific influence on, realizing its national interests. It is Russia, in our opinion, that plays a unifying role, ensures the establishment of an equilibrium partner dialogue between East and West, which should meet in accordance with the international agenda formulated by Russia and the proposed picture of the world.

The ancient medicinal category-drugs based on medicinal plant raw materials (MPRM), has not lost relevance today. The production of such drugs is constantly developing and they have a pharmacopoeial status in many states. Trends in the devel- opment of medical science are manifested not only in the complexity of the latest pharmaceutical technologies, hut also in a deep knowledge of the mechanisms of action of natural products, especially in long-term and chronic diseases of various genesis. In the general structure of morbidity, pathology of the musculoskeletal system occupies one of the leading places. Diseases of the spine, bones and joints are equally characteristic of both young and old people. Almost every tenth adult has one or another pathology of the musculoskeletal system. In the process of numerous selection and research of combinations of various medicinal plant raw materials with antiinflammatory, regenerative and consequently anti-arthritic and anti-arthrotic activity and screening for Parametium caudatum, a combination of 13 objects was selected. All of them contain flavonoids, which are the main "carriers" oj pharmacological activity. The optimal extractant for the flavonoids extracting is 70% ethanol. To select the extraction method, the maceration (Method 1) and percolation (Method 2) were studied. The values are comparable, but taking to account that the first method is more common and does not require a long extraction as in percolation, maceration was chosen.

The article is devoted to the application of stress testing methods to assess the risk of possible bankruptcy of tourist companies at the regional level.
