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

Sensors (Basel)
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 ...

Modelica-Based Modeling on LEO Satellite Constellation

Linköping Electronic Conference Proceedings, 2021
The new generation of LEO (Low Earth Orbit) communication satellite constellations have the advantages of low latency, strong signals, and global coverage. In order to achieve global coverage, the LEO satellite constellations are often very large, with a large number of satellites, which puts forward high requirements for the overall design, operation ...

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.

LTE‐based satellite communications in LEO mega‐constellations [PDF]

International Journal of Satellite Communications and Networking, 2018
SummaryThe integration of satellite and terrestrial networks is a promising solution for extending broadband coverage to areas not connected to a terrestrial infrastructure, as also demonstrated by recent commercial and standardisation endeavours. However, the large delays and Doppler shifts over the satellite channel pose severe technical challenges ...

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 ...
