Description
Activity: GSTP
ESA TO: Mr. Martin Hiller - Software Systems Division
Led by the ESA/ESTEC IMA-SP program, this study – namely In-Flight Hosting of Prototype Applications (IHPA) project – presents an experiment of Flight Software partitioning in an Integrated Modular Avionics for Space (IMA-SP) system. This experiment also tackles the maintenance aspects of IMA-SP systems.
The fundamental objective of this experiment is to demonstrate through a representative use case that the successful IMA concepts deployed in the civil aviation industry is also beneficial to Space Avionics and in particular to the OBSW developments and life-cycle. The main objectives are however to explore and to demonstrate approaches for software maintenance of an IMA-SP system.
The presented case study is PROBA-2 Flight Software. The study addresses and discusses the following subjects: On-Board Software Maintenance in IMA-SP, boot strategy for Time and Space Partitioning, considerations about the ground segment related to On-Board Software Maintenance in IMA-SP, and architectural impacts of Time and Space Partitioning for PROBA software’s.
In the field of embedded system, the term OBSW Maintenance (OBSM) basically consists in updating whole or parts of the system or application software or data. In an IMA-SP environment, it concerns the partitioning kernel as well as the system and application partitions. The goal is then to be able to update any individual partition independently of the others.
Finally, this presentation shares the results and the achievements of the study and it appeals at further perspectives for IMA-SP and Time and Space Partitioning.
