Nongeostationary mega-constellations have the potential to offer low-latency services to under-served geographical areas and aeronautical/maritime sectors. This will be enabled through a constellation involving low Earth orbit (LEO) fleet of satellit

Are Low Earth Orbit Constellations the Next Step in Deploying Mobile-TV?

Autor: Jean-Didier Gayrard

Publikováno v: 25th AIAA International Communications Satellite Systems Conference (organized by APSCC).

In Europe, operators have started the deployment and commercialization of the third generation (3G) of mobile systems. For the time being, only terrestrial infrastructures are deployed despite the possible benefits of a satellite component. Up to now
