Fryz S. Methodology of Operational Process Control in Satellite Telecommunication Systems

The object of study - the process of satellite telecommunication systems, and the subject of study - process management in satellite telecommunication systems in solving operational problems. The aim - to maximize efficiency of process management in satellite telecommunication systems in solving operational problems in conditions of limited onboard resources. The thesis used methods of formalization, optimization, analysis, synthesis, expert assessments, simulations and physical experiments. The processes of target information receipt, which take place in the systems, have been formalized, and mathematical models, which adequately represent attendance of the specified surface facilities and provide respective analytical calculations, have been developed. Based on the modeling results, the author has proposed appropriate methods for ensuring the desired attendance efficiency for the mentioned surface facilities, which is focused on the efficient operation of orbital equipment and control of target information receipt processes. The author has developed methods for practical routes generation enabling attendance of the specified surface facilities based on the spacecraft angular motion control, and suggested possible options for combined use of domestic and foreign satellite telecommunication systems as one of the ways to ensure the required efficiency of surface facilities attendance. The results introduced in five institutions.
