Editing RapidIO (section)

The interconnect or "bus" is one of the critical technologies in the design and development of spacecraft avionic systems that dictate its architecture and level of complexity.  There are a host of existing architectures that are still in use given their level of maturity.  These existing systems are sufficient for a given type of architecture need and requirement.  Unfortunately, for next generation missions a more capable avionics architecture is desired; which is well beyond the capabilities levied by existing architectures.  A viable option for the design and development of these next generation architectures is to leverage existing commercial protocols capable of accommodating high levels of data transfer.

In 2012, RapidIO was selected by the Next Generation Spacecraft Interconnect Standard (NGSIS) working group to serve as the foundation for standard communication interconnects to be used in spacecraft. The NGSIS is an umbrella standards effort that includes RapidIO Version 3.1 development, and a box level hardware standards effort under [[VMEbus International Trade Association|VITA]] 78 called SpaceVPX or High ReliabilityVPX. The NGSIS requirements committee developed extensive requirements criteria with 47 different elements for the NGSIS interconnect. Independent trade study results by NGSIS member companies demonstrated the superiority of RapidIO over other existing commercial protocols, such as InfiniBand, Fibre Channel, and 10G Ethernet. As a result, the group decided that RapidIO offered the best overall interconnect for the needs of next-generation spacecraft.<ref>{{cite web |url=http://www.responsivespace.com/Papers/RS2013/Sessions/SESSION%20I/1005_Collier/1005P.pdf |title= Next Generation Space Interconnect Standard (NGSIS): A Modular Open Standards Approach for High Performance Interconnects for Space |author=Patrick Collier |date=14 October 2013 |page=5  |publisher=Reinventing Space Conference |access-date=9 October 2014}}</ref>
