SpaceWire for On-boarding Processing Applications

SpaceWire (SpW) grown organically from the needs of on-board processing applications. It's a network of spacecraft/aerocraft with Routers.

Instead of customization in builting system on a project-by-project basis resulting in long development at high cost and risk, SpaceWire focused on the definition of an network architecture for payload data systems. Processing units, mass-memory units and down-link telemetry systems developed for one mission can be readily used on another mission, reducing the cost of development, improving reliability.
(SpaceWire is currently being installed on several NASA and European Space Agency (ESA) spaceships to support onboard communications during space missions.

SpaceWire standard has taken into consideration two existing standards, IEEE 1355-1995 and ANSI/TIA/EIA-644.
