Description
Space industry and Agencies have expressed the need to raise the level of standardization in the spacecraft avionics systems in order to increase efficiency and reduce development cost and schedule. This has been materialized by some initiatives and one main example is a common approach under the Space Avionics Open Interface Architecture (SAVOIR) initiative. In on-board spacecraft architectures, networks have become more and more complex with the multiplication of protocols: MIL-STD-1553 bus, CAN bus, SpaceWire, SpaceFibre, Ethernet. Today, there are multiplying On-Board Communication links creating scenarios in which a simple margin is not enough for the design. The emergence of System-On-Chip enables to manage several communication architecture on-board generating a lot of communication interaction. While the on-board architecture is evolving, design and simulation tools evolve in the same way That is why new tools are developed such as the OSRA-ION (Integrated On-Board Network) toolchain, which is now extensively used in all future studies in Thales Alenia Space Avionics team.
