Integrated Modular Avionics for Spacecraft Software Architecture and Requirements
Abstract
Space industries designers, for scientific, observation, exploration and telecom missions are now facing requirements such as long lifetime, autonomy and safe operation guarantee in case of failure. New technical and industrial challenges will add complexity. The key point to ensure the success of future industrial projects is to answer on board processing increasing demand by designing more scalable and modular architectures in order to allow new missions whilst improving lifecycle, costs of design, qualification, and security.Focusing on data processing, new technology such as time and space partitioning as part of Integrated Modular Avionics (IMA) experimented by aeronautical domain and industrialized in the new generation of aircraft, was analyzed first for security and feasibility in space domain by an ESA project on secure partitioning and working group. In order to complete these studies, Integrated Modular Avionics for Space, as current ESA project, has the objective to confirm the feasibility of Time and Space Partitioning in space domain using existing hardware and based on ARINC653.By combining the efforts of industrial partners, the IMA for Space (IMA SP) project main goals are to focus first on some major topics such as computational model, impact of caches, impact on process and tools, Failure Detection and Isolation Recovery (FDIR), maintenance and I/O management in order to consolidate requirements, then to develop software solutions that meet requirements and lastly to implement these solutions in a demonstration phase with operational software.
