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.

STAR-Dundee设计用于机载航天器的信号和图像处理系统以及数据通信网络。STAR-Dundee在SpaceWire航天器机载网络技术的研究和开发中发挥了主导作用，该技术目前已在100多艘航天器上使用。目前，该公司正在研究下一代高性能、高可用性的航天器网络技术“太空纤维”，该技术可以在电力或光纤电缆上运行。spacefiber将用于将航天器上的图像和其他传感器与机载处理和数据存储子系统互连。OCIPSA项目将研究和开发用于空间应用的光通信技术和图像处理技术。它将探索在高可用性空间光纤网络中使用光纤，考虑通道和链路冗余，以提供航天器所需的高可靠性和高可用性能力。实验预计将包括驱动光纤的数字通信协议引擎的设计（在fpga的VHDL中），容错网络的构建，图像传感器和图像处理应用的集成，以及光纤网络在瞬时，持久和永久通道和链路故障情况下的性能的总体评估。
