On the Use of Low Earth Orbit Satellite Constellations for Offshore Communication

The goal of this research is to obtain time and location dependent network performance information of Low Earth Orbit (LEO) satellite constellations in (primarily) offshore areas that helps the marine industry to select suitable satellite providers for their future operations. 

The maritime sector currently pushes developments that involve down-manning of vessels and the use of autonomous and remote technologies.  Fast (real-time) and/or high capacity data transfers are required which is not achievable with conventional geostationary (GEO) satellites.

The performance of four LEO satellite constellations (SpaceX, OneWeb, Telesat and Kuiper) have been simulated in this research and compared with GEO solutions. It turns out that LEO constellations surpass GEO satellites from their second deployment phase onward and can provide continuous global coverage, in real time, provided that two remote operation centres are operational at opposite sides of the Earth.
