SHARING A UNIQUE COMPUTING PLATFORM BETWEEN A PAYLOAD AND A PLATFORM SOFTWARE USING IMA-SP

摘要

Following the Integrated Modular Avionics paradigm used in the aeronautical world for20 years, the ESA IMA-SP study aimed at evaluating the applicability of this approach to the spacedomain. THALES ALENIA SPACE and SCISYS worked on a common use case aiming at sharing asingle computing platform between a payload and a platform software using the IMA for Spaceparadigm and building block implementation defined in earlier phases of the study. This paperaddresses all aspects of the use case from system requirements, development process, to buildingblock specification and implementation, and provides recommendations based on the lessonslearned during the use case realization.
