Optical Communication and Image Processing for Space Applications (OCIPSA)

STAR-Dundee designs signal and image processing systems and data communications networks for use on-board spacecraft. STAR-Dundee played a leading role in the research and development of the SpaceWire spacecraft on-board network technology, which is now being used on more than 100 spacecraft. It is currently working on the next generation, high-performance, high-availability spacecraft network technology, SpaceFibre, which can run over electrical or fibre optic cables. SpaceFibre will be used to interconnect image and other sensors on-board a spacecraft to the on-board processing and data-storage sub-systems. The OCIPSA project will research and develop optical communication technology and image processing technology for space applications. It will explore the use of fibre optics in high-availability SpaceFibre networks, considering lane and link redundancy to provide the high reliability and high availability capabilities required on-board a spacecraft. Experimentation is expected to include the design (in VHDL for FPGAs) of digital communication protocol engines driving fibre optics, the construction of fault tolerant networks, the integration of an image sensor and image processing application, and the overall evaluation of the performance of the fibre optic network in the event of transient, persistent and permanent lane and link failures.
