Abstract
This memo presents the current deployment of network coding in some
satellite telecommunications systems along with a discussion on the
multiple opportunities to introduce these technics at a wider scale.

1. Introduction
Network coding schemes are inherent part of the satellite systems,
since the challenging physical layer require specific robustness to
guarantee an efficient usage of the expensive radio resource.
Further exploiting these schemes is an opportunity for a better end
user experience along with a better exploitation of the scarce
resource.
In this context, this memo aims at:
o summing up the current deployment of network coding schemes;
o identifying opportunities for further usage of network coding in
satellite systems.
1.1. Glossary
The glossary of this memo is related to the network coding taxonomy
