OBC-SA stands for On-Board Computer System Architecture
The project is supported by the German Aerospace Center's Space Administration with funding from the Federal Ministry for Economic Affairs and Energy. The project involves the following partners: Airbus Defence & Space, Fraunhofer FOKUS, STI, SYSGO and TTTech.
The OBC-SA project is developing an architectural framework for future on-board computer systems to enable the modular integration of systems with different performance and functional characteristics into the IT infrastructure of a spacecraft. To this end, the project partners are developing a demonstration system consisting of two fault-tolerant on-board computers. One computer is based on the Intel Atom® processor with a Triple Modularity Redundancy (TMR) architecture and the seconds is a Dual Modular Redundancy (DMR) system with the high-end P4080 embedded multicore processor from Freescale. They use the PikeOS real-time operating system, which also supports the partitioning of the P4080 processor's resources.
SYSGO's role within the project is to deliver BSPs for two demonstrator platforms: x86 Atom & Freescale P4080.
