Standardized SpaceWire solutions for next generation systems

SpaceWire is leveraged as one of three main fabrics in SpaceVPX, a new system physical interconnect and form factor standard nearing completion at VITA. RapidIO and I2C along with heritage CompactPCI enable space systems to be built with full single point fault tolerance yet leverage the existing OpenVPX infrastructure for prototyping and test. SpaceVPX is described along with new network components under development that together may be applied across a large range of spaceborne electronics mission needs yet providing interoperability, scalability and future upgrade savings.
