Joint Power and Tilt Control in Satellite Constellation for NGSO-GSO Interference Mitigation

open access: yesIEEE Open Journal of Vehicular Technology, 2023
The number of non-geostationary orbit (NGSO) satellite constellations is growing persistently. Accordingly, co-channel interference with geostationary orbit (GSO) networks will inevitably affect the operation of NGSO and GSO satellites in the years to ...

An Updated Comparison of Four Low Earth Orbit Satellite Constellation Systems to Provide Global Broadband

open access: yes2021 IEEE International Conference on Communications Workshops (ICC Workshops), 2021
Twenty years of technological improvements have raised once again the question of the economic viability of offering Internet access from space using non-geostationary orbits (NGSO). Trying to answer this question, many established satellite operators (e.
