Hierarchical Resource Management for Mega-LEO Satellite Constellation [PDF]

Sensors
The mega-low Earth orbit (LEO) satellite constellation is pivotal for the future of satellite Internet and 6G networks. In the mega-LEO satellite constellation system (MLSCS), which is the spatial distribution of satellites, global users, and their services, along with the utilization of global spectrum resources, significantly impacts resource ...

Satellite-enabled LTE systems in LEO constellations [PDF]

2017 IEEE International Conference on Communications Workshops (ICC Workshops), 2017
LTE-based satellite systems in LEO constellations are a promising solution for extending broadband coverage to areas not connected to a terrestrial infrastructure. However, the large delays and Doppler shifts over the satellite channel pose severe technical challenges to a traditional LTE system.

GaliLEO: A Simulation Tool for LEO Satellite Constellations [PDF]

SIMULATION, 2002
The authors present GaliLEO, a simulator for the transmission of connection-oriented traffic over a constellation of LEO/MEO (low/medium earth orbit) satellites. Its scope is limited to the satellites and the stations accessing them, without any modelling of the terrestrial network, but inside this scope the goal is to study the performance of ...
