Satellite Network Simulator 3 (SNS3) is a satellite network extension to Network Simulator 3 (ns-3) platform. ns-3 is a discrete event simulator for networking research licensed under General Public License v2 (GPLv2). SNS3 models a full interactive multi-spot beam satellite network with a geostationary satellite and transparent star (bent-pipe) payload. The reference satellite system consists of 72 spot-beams with an European coverage, 5 gateways and Ka-band frequencies. It implements the DVB-RCS2 – DVB-S2 standards.
This platform has been initially developed by Magister Solutions Ltd in the frame of ESA ARTES european projects (AO6947, AO7476).
It is now also promoted by CNES (French Space Agency) as a reference open-source software tool within its research and development studies and activities in the domain of satellite communication systems and networks.
