Speaker
Mr
Julien Galizzi
(CNES)
Description
The lessons learnt from the CNES projects are that the institutes involved in the payload developments have to systematically develop general “non-scientific” features, such as boot, platform interface, FDIR, I/O, timing, mass memory interface, etc. CNES have therefore initiated some years ago generic developments in order to offer off-the-shelf building blocks that could be easily reused with a low level of adaptation effort, aiming therefore at decreasing the cost of the mission, and increasing the reliability of the payload developments. The institutes can consequently concentrate their efforts on real science, high degree of expertise, especially on the science mission on-board software application part rather than “housekeeping” features. The presentation will describe the technical choices that have been made in order to provide a high level of genericity enabling a clear and effective decoupling between “housekeeping” and science, thanks to Time & Space Partitioning. It will provide status of development of the various building blocks, including visibility on current real but also future use cases and how TSP could efficiently help to solve budget constraints and to optimize the avionics architecture.
