OSRA - Onboard Software Reference Architecture

 

logo OSRAThe Onboard Software Reference Architecture (OSRA) is a comprehensive reference architecture for spacecraft onboard software which is intended to address the major needs for software development in a modern, European context. The OSRA uses a component- and model-based approach to allow the development in a more efficient and flexible way than traditional methods, without sacrificing robustness.

 

OSRA has been developed in the frame of the SAVOIR initiative (see the SAVOIR project on this ESSR), in order to reply to industrial needs that can be summarised as FASTER: reduce schedule, LATER: allow for late changes in the life cycle and SOFTER: ease subcontracting of part of the software.
 

Software

      - Space Component Model Metamodel: The reference implementation of the component model for the OSRA is based on an ecore metamodel, called the Space Component Model (SCM).
      - SCM Model Editor: A graphical editor based has been developed to allow the creation of SCM models. The so called OSRA SCM Model Editor is based on Eclipse, using the Sirius framework.
