Deterministic SpaceWire / SpaceFibre ? The challenge !


TELETEL has been awarded with a new ESA contract in the area of onboard data networks. In co-operation with Airbus Defence & Space, Thales Alenia Space and RUAG, TELETEL (prime contractor) will define a deterministic protocol layer for SpaceWire and SpaceFibre networks. The main objective of the activity is the development of a novel deterministic protocol layer for SpaceWire and SpaceFibre that works primarily at network level (i.e. within routing switch devices), allowing therefore to build fully deterministic networks with both protocol-aware and legacy SpaceWire/SpaceFibre nodes.

The work is being performed under the ESA study entitled “SpaceWire Network Management Service Suite definition and validation”. Additionally, TELETEL as a contributing member of the Spacewire/SpaceFibre Working Group will work closely with the group in order to achieve maximum endorsement by the global SpW/SpFi community.
