A new method to estimate GPS satellite and receiver differential code biases using a network of LEO satellites

, 2021
The differential code biases (DCBs) of the global positioning system (GPS) receiver onboard low-Earth orbit (LEO) satellites are commonly estimated by a local spherical symmetry assumption together with the known GPS satellite DCBs from ground-based ...

Multiservice on-demand routing in LEO satellite networks [PDF]

IEEE Transactions on Wireless Communications, 2009
In this paper, a distributed on-demand routing protocol for Low Earth Orbit (LEO) satellite systems, named multiservice on-demand routing (MOR), is proposed and evaluated. The proposed protocol adjusts the routing procedure to the QoS requirements of different traffic classes.

Switched Ethernet Networking over LEO Satellite [PDF]

2005 2nd International Symposium on Wireless Communication Systems, 2005
Satellite onboard switching capabilities, and their possibility to enable "over-the-air" networks, are a strongly innovative achievement of modern satellite communication. The exploitation of satellite networking is especially relevant in the case of low Earth orbit satellites (LEO), where the reduced latency makes a LEO mesh network highly appealing ...

On routing for extending satellite service life in LEO satellite networks [PDF]

2014 IEEE Global Communications Conference, 2014
We address the problem of routing for extending the service life of satellites in Iridium-like LEO constellations. Satellites in LEO constellations can spend over 30% of their time under the earth's umbra, time during which they are powered by batteries. While the batteries are recharged by solar energy, the depth of discharge they reach during eclipse

Distributed Massive MIMO for LEO Satellite Networks

IEEE Open Journal of the Communications Society, 2022
The ultra-dense deployment of interconnected satellites will characterize future low Earth orbit (LEO) mega-constellations. Exploiting this towards a more efficient satellite network (SatNet), this paper proposes a novel LEO SatNet architecture based on distributed massive multiple-input multiple-output (DM-MIMO) technology allowing ground user ...
