Subscriber and inter-satellite paths in LEO communications networks

The purpose of the study is to propose and substantiate technical solutions for inter-satellite and subscriber paths of loworbit communication networks. There is a prospect of commercial use of such networks; therefore, the current stage of low-orbit satellite communications development is characterized by an increase in efforts to put the projects into practice. As part of the study, solutions for inter-satellite paths (ISP) in low-orbit communication systems and solutions that increase the capacity of their subscriber paths are considered. It is noted that ISPs can be built on the basis of radio and optical bands equipment. In this regard, the advantages and disadvantages of each case are considered. The expediency of constructing subscriber paths based on radio band equipment and the preference of constructing ISP based on optical band equipment are substantiated. The relationship between the feasibility of increasing the capacity of subscriber paths and the capabilities of ISP in terms of reliability and bandwidth is established
