Non‐Geostationary Satellite Orbit (NGSO) Communications Systems are satellites which move in relation to the Earth's surface. Until recently they had limited use for communication applications because their systems were complex. Based on recent technological evolutions, it is now possible to create a chain production of cheaper NGSO satellites that can have a much shorter lifespan so that the satellite infrastructure can be upgraded more regularly. This evolution opens up a plethora of opportunities for massive self-organized, reconfigurable and resilient NGSO satellite constellations. The idea is to create a global network comprising a large number of NGSO satellites to provide ubiquitous broadband connectivity.
From architectures to specific use-case-oriented communication design, key technologies, management mechanisms and security, the authors give a broad overview of the latest research and advances in NGSO Communications Systems.
