Abstract
The article develops a methodology for scheduling an orbital channel resource with operational priority assignment based on the calculation of the parameters of a non-Markov service model with a limited residence time of a request in the system, which differs from known methods in that it takes into account the priority of various network subscribers, taking into account the high dynamics of their movement and the average waiting time in the service system with priority in the allocation of the orbital channel resource of the satellite command-relay system. The analysis of the influence of service quality indicators of information data flows is carried out.It is shown that the developed method of priority scheduling makes it possible to meet the requirements for the quality of service. A complex of experimental studies was carried out, which showed the possibility of ensuring the required level of stability with the deterioration in difficult conditions of radio electronic equipment, which made it possible to formulate practical proposals for improving the complex of coordination and distribution of resources of in the satellite command relay system.

Использование разработанной методики позволяет обеспечить требуемые показатели качества обслуживания приоритетных потоков информационных данных и за счет этого обеспечить требуемую связность системы и, соответственно, устойчивость спутниковая командно-ретрансляционная система (СКРС) в целом
Summary
Аннотация: В статье разработана методика диспетчеризации орбитального канального ресурса с оперативным назначением приоритетов на основе расчета параметров немарковской модели обслуживания с ограниченным временем пребывания заявки в системе. Сделаны выводы об особенностях этапа координационного планирования средств подсистемы ретрансляции, заключающихся в распределении орбитального канального ресурса СКРС на основе немарковских приоритетных систем обслуживания.
