The latest and next generations of spacecraft synthetic aperture radar and high-resolution image instruments will provide very high data-rates on-board a spacecraft, in excess of 10 Gbps. SpaceFibre is the next generation of SpaceWire network technology for spacecraft on-board data-handling. It runs over electrical or fibre-optic cables, operates at very high data rates, and provides in-built quality of service (QoS) and fault detection, isolation and recovery (FDIR) capabilities. This paper describes three SpaceFibre based units: an image sensor, an FPGA based processor and a many-core DSP processor. Equipped with SpaceFibre interfaces they demonstrate the ease with which SpaceFibre can be deployed on future space missions.

A high-performance FFT processor for spectrometer applications in space has been designed, implemented and tested. The wideband spectrometer five (WBS V) implements a 1 k-point FFT in a Microsemi RTG4. Operating with dual 2.4 Gsamples/s ADCs it provides 2 GHz bandwidth with a FFT bin size of 2.4 MHz. The architecture, implementation and results of this spectrometer are described.
