Time and Space Partitioning in Spacecraft Avionics
This paper will describe the benefits of incorporating software Time and Space Partitioning (TSP), based upon the aeronautic IMA concept, into the spacecraft avionics architecture to manage the growth of mission functions implemented in the on-board software. The paper addresses how TSP can be used to safely integrate applications of different criticality and security classifications, and how incremental validation is supported to control the impact of software modifications to the system.
