LEO-Ring-Based Communications Network

This paper continues the development of a concept for a low-earth-orbit-based optic-fiber-communication system that may ameliorate some limitations of present space communications systems. Starting with an assumption that a circum-terra ring can be deployed in LEO, a high-bandwidth, optical-fiber-based, communication system has been proposed as the first of a system of LEO and higher-orbit (MEO) rings for different purposes. These rings about the Earth would complement existing terrestrial and space communications networks and thereby improve global connectivity and throughput. In particular, networking issues necessary for both initial and expanded-ring system communications are addressed.
