Рассматриваются условия нагружения зеркальных антенн воздушным потоком и тепловыми воздействиями с учетом вариабельности пространственного положения конструкции. Предложена концепция построения цифровых моделей нагруженности крупногабаритной прецизионной антенны наземных систем спутниковой связи. Определены возможности их интеграции в контуры принятия решений для интеллектуальной поддержки стадии эксплуатации. The conditions for loading reflector antennas with air flow and thermal effects are considered, taking into account the variability of the spatial position of the structure. A concept is proposed for constructing digital models of the loading of a large-sized precision antenna for ground-based satellite communication systems. Possibilities of their integration into decision-making contours for intelligent support of the operation stage have been determined.

The technical aspects of the main promising projects in the segments of medium and low-orbit satellite communication systems are considered, as well as the project of the domestic low-orbit information and telecommunications system using the terahertz range, which is based on the use of satellite platforms of the micro- and nanosatellite class and the distribution of functional blocks of complex satellite payloads more high-end on multiple functionally related satellites. The proposed system of low-orbit satellite communications represents the groupings of low-orbit spacecraft (LEO-system) with the architecture of a "distributed satellite", which include the groupings of the root (leading) satellites and satellite repeaters (slaves). Root satellites are interconnected in a ring network by high-speed links between the satellites. The geometric size of the “distributed satellite” is the area around the root satellite with a radius of about 1 km. The combination of beams, which are formed by the repeater satellites, make up the service area of the LEO system. The requirements for the integrated service area of the LEO system (geographical service area) determine the requirements for the number of distributed satellites in the system as a whole. In the proposed system to reduce mutual interference between the grouping of the root (leading) satellites and repeater satellites (slaves) and, accordingly, minimizing distortions of the information signal when implementing inter-satellite communication, this line (radio channel) was created in an unlicensed frequency (e.g., in the terahertz 140 GHz) range. In addition, it additionally allows you to minimize the size of the antennas of such a broadband channel and simplify the operation of these satellite systems.
