Satellite Network Simulator 3 (SNS3) is a satellite network extension to Network Simulator 3 (ns-3) platform, that was developed within ESA ARTES 5.1 AO6947 project, “Development of an Open-Source, Modular and Flexible Satellite Network Simulator” (2012 – 2014). 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.
SNS3 is a dynamic system simulator, which works at a physical level burst resolution. Its use cases range from full network level performance to a single user Quality of Service verification. SNS3 is built to be modular and flexible to provide extensibility to different satellite communication networks and use cases.
Secure multicast services on top of multi-spot beam satellite networks is an attractive combination. The services can benefit from the inherent advantages of the satellite system, such as large coverage area, as well as effective multicast transmissions. However, security solutions must address multi-spot beam interactive satellite system specific challenges to offer seamless access for the users. In ESA ARTES 5.1 AO7476 project, “Network Security on Multi-Spot Beam Broadband Networks for Multicast Based Interactive Systems” (2014-2016) secure multicast service delivery architecture was developed and an end-to-end performance assessment of secure multicast service delivery over multi-spot beam geostationary satellite network was carried out. The security framework relies on IP security with multicast extensions and Group Domain of Interpretation (GDOI) multicast key management. Several performance enhancements are proposed for the delivery of secure interactive unicast/multicast services on top of multi-spot beam satellite networks and their performance are analysed with extensive network level simulations. Magister Solutions was prime in the project and VTT Technical Research Centre of Finland as a subcontractor.
In ESA TRP AO8045 project, “Robust TM System for Future Launchers” (2015-2016) objective was to find suitable concepts for an advanced launch vehicle telemetry system with improved robustness, performance and power efficiency, and to identify technical and technological steps required for later development. Magister Solutions developed a system level simulator (SLS) on top of network simulator 3 (ns-3) to study the performance of different techniques and compared the performance results with the initially defined (and achieved) requirements. Project consortium consisted of Magister Solutions and VTT Technical Research Centre of Finland from Finland and Space Engineering and ELV from Italy.
Telecommunication Satellite systems are raising in complexity: new LEO constellation projects are under development, targeting not only low speed data collection or mobile communications, but also broadband and broadcast services. Mastering the cost of these constellations and at the same time being able to assess the offered Quality of Service is critical to secure the business case of the satellite operator.
The objective of the ESA AO8939 project, “Real-time Satellite Network Emulator” (2018 – 2021) is to enable the study and assessment of protocol performances used in these new constellations, in particular routing protocols which may affect the end to end quality of service.
The project activities include the design of a library of satellite network elements (e.g. routers, interfaces), the development of a controlling interface and an orchestrator in charge of the coordination of the orbital and network simulations. Project consortium consists of Airbus Defence and Space France, VTT Technical Research Centre of Finland and Magister Solutions.
