Model of the low-orbit communication system operation

Relevance of this topic is caused by the need to exchange heterogeneous broadband information between the space stations, spaceships and the ground facilities. The paper considers a low-orbit communication system with the ballistic structure ordered by a hexagonal scheme. It proposes such a solution as an alternative to the satellite systems positioned in a geostationary orbit. Characteristics of the inter-satellite optical and subscriber radio paths are assessed. Alterations in the power characteristics and frequency shifts in the paths are analyzed taking into account motion dynamics of the system satellites. The provided assessments are based on characteristics of the promising components that have undergone flight testing.
