"Scientific Computing in Space Using COTS Processors"

Jeremy Ramos. Roger Sowada, and David Lupia


The application of commercial-off-the-shelf (COTS) processing components in operational space missions with optimal performance and efficiency requires a system-level approach. Of primary concern is the need to handle the inherent susceptibility of COTS components to Single Event Upsets (SEUs). Honeywell in conjunction with selected hardware and software providers is developing an approach to enable space based scientific computing using high performance COTS hardware and software. The approach addresses maintainability of system availability and throughput in the harsh space environment. This paper will present the hardware and software approach to enable this technology. Topics will include: software trades, architecture and implementation, hardware trades, architecture and implementation, validation concepts and implementation.
