    New software technology in space: BOSS – a dependable open source embedded operating system
    (INFORMATIK 2003 - Mit Sicherheit Informatik, Schwerpunkt "Sicherheit - Schutz und Zuverlässigkeit", 2003) Montenegro, Sergio
    BOSS targets a principle which the world forgot a long time ago: Simplicity. BOSS is an embedded real time operating system for safety critical applications. Our experience shows that the first enemy of safety is the complexity. If you need safety, use only what you can understand. This was the philosophy creating BOSS. First: build every thing as simple as possible. Second: use modern framework technology to reduce the complexity of the applications. Third: use component technology to be able to handle the remaining complexity. The result is very promising. BOSS is already working for years without interruptions, for example in space (Satellite BIRD [BIRD0]), in medical devices, protocol tester and other Applications [ROD03]. Furthermore BOSS is opensource, so you can look inside, adapt it and move to other platforms/hardware.

    In many cases, similar challenging problems arise in different domains and are often solved with an only limited focus. Synergy effects between different research fields can lead to an enormous technical improvement. This is illustrated by combining experiences and competencies of the institute of Space Systems and the institute of Transportation Systems of the German Aerospace Center (DLR). Their cooperation/collaboration aims at more reliable and highly available platforms for embedded (software/hardware) systems. Both institutes have developed software frameworks to be used in embedded systems of their field of work. In this paper we present an approach of integrating an embedded real time OS to be used in satellites into the DOMINION implementation-platform, which is used for the specification of embedded in-vehicle software. Finally a safety critical application with hard real time requirements will be chosen as a use-case to demonstrate the combination of aerospace and automotive technologies.
