Adaptability and Survivability in Spaceborne Time-and Space-Partitioned Systems

Abstract-Future space missions call for innovative computing system architectures, meeting strict requisites of size, weight, power consumption (SWaP), cost, safety and timeliness. To answer the aerospace industry interests, especially the European Space Agency (ESA), the AIR (ARINC 653 in Space Real-Time Operating System) architecture has been defined, following the advanced notion of time and space partitioning (TSP). In order to achieve adaptability and survivability in the face of environmental changes or new mission requirements, it is of paramount importance that onboard computing systems are reconfigurable. In this paper we present recent and ongoing developments on AIR Technology to achieve adaptability and survivability of AIRbased systems, and a methodology for onboard software update in order to add new features to the mission plan
