Abstract :
SpaceWire-R is a protocol that provides onboard applications with reliable high-speed data transfer services over SpaceWire links especially for mission data transmission between sensors and data recorders. Independent implementations on different hardware with reference to the draft specification have been succeeded in interoperability test, which resulted in consolidating the protocol. The final specification document has been under preparation by JAXA. The present paper describes a result of interoperability test and evaluation of SpaceWire-R performed from 2013 to 2014.
