On-Board Computer System Architecture
Oct. 01, 2012 to Sep. 30, 2014
Computer systems for space flight applications require ever increasing amounts of computing power to enable (on-the-fly) preprocessing of large data sets from sophisticated experiments and payloads, or even to perform real time computation of safety-critical control commands. Without this, spacecrafts would be unable to perform complex docking maneuvers or landing approaches autonomously. Besides meeting high performance requirements, the on-board computer systems must also provide interfaces that allow their embedment in a spacecraft´s often redundant communications infrastructure or support redundant ports for instruments with very high data transfer rates in the gigabit range.
With this in mind, the On-Board Computer System Architecture (OBC-SA) project is developing an architectural framework for future on-board computer systems to enable the modular integration of systems with different performance and functional characteristics into the IT infrastructure of a spacecraft.
