The SAVOIR Advisory Group decided to spawn a specific subgroup on on-board software reference architectures called “SAVOIR Fair Architecture and Interface Reference Elaboration" working group.

This subgroup achieves the definition of software reference architectures, based on open interface standards, for the purpose of specifying building blocks that can be developed, qualified and composed into compliant avionics software systems with a minimum of re-engineering effort, providing a maximum of reliability and performance and simple to use and to implement. It acts as design authority for current R&D activities, provides recommendations to future R&D activities and provides the SAVOIR Advisory Group with a synthesis of the results.

The major SAVOIR-FAIRE output are:

• software reference architecture
• space component model specification
• execution platform specification
• software functional chains generic specification
