Future manned systems advanced avionics study COTS for space

COTS/sup +/ has been defined as commercial off-the-shelf (COTS) products, ruggedized and militarized components, and COTS technology. The study cites the benefits of integrating COTS/sup +/ in space, postulates a COTS/sup +/ integration methodology, and develops requirements and an architecture to achieve integration. Developmental needs and concerns were identified throughout the study. A total COTS/sup +/ system concept consisting of COTS/sup +/ hardware, software, systems, architecture, and their requirements is described. The concept was implanted from the bottom up into conceptual space avionic architectures representing different future manned mission vehicles. The bottom-up integrations met with future manned mission top-down requirements that were also developed in the study. Compatibility differences were resolved by changes to mission/vehicle requirements, architecture, and/or COTS/sup +/ product/testing requirements.<
