Why mention Telecommunications?
Telecommunications has been our historical commercial driver for powerful & flexible on-board processing
It embodies a set of skills and technologies that can support flexible & fast on-board processing demands in other space application domains
E.g. Gaia Astrometry Video Processing Unit (a well-defined problem)
Dec 2010 - 8
Taking Advantage of Enabling Technologies
High bandwidth ADCs and DACs (1 to 4 GHz becoming common)
High integration and low power Rad-Hard ASIC technologies (e.g. 45nm)
Reconfigurable Rad-Tolerant FPGAs (flexible and high integration)
Low power Rad-Hard one-time programmable FPGAs (efficient and provide the simplest solution to a custom flight chip)
Multi-Gigabit wired communication links (low power and mass)
High speed Micro-Processors (designed for robustness when used in high radiation environments ; versatile as they are software driven)
High capacity and robust solid state storage devices (low power, no moving parts, reliable, low mass)

Payload Processing and Collaboration
To start to bring this power to bear on other space science & Earth Observation problems we generally seek relevant external collaboration…especially to tension processing resources against science return
…and where there isn’t an immediate commercial opportunity we also seek mechanisms to make them work
Various examples at present: DRPM (dynamically reconfigurable processor module) with Univ.
Brunswick for ESA CEOI flexible on-board processing study for EO instruments, with
NOC Southampton Wideband spectrometer (ORTIS back end) with Univ. Dundee &
RAL & Oxford for ESA TIDAS with University of Leicester, Selex Galileo & RAL
Dec 2010 - 12
Scientific Processor Application Areas
Instrument back-end processing Image compression and data compaction High speed data analysis (e.g. FFT’s, resampling, imaging processing, navigation and
locomotion processing etc.)
Data management and Instrumentation control Mass memory storage and data accessing Multi-instrument control and monitoring Redundancy and failure mitigation handling
Advanced payloads Demanding applications (e.g. digital beamforming for SAR, high resolution sensor post-
processing etc.) Reconfigurable processing platforms (e.g. Chameleon processing units)

Created in 2007 as a result of joint support from the Natural Environment Research Council (NERC), the Technology Strategy Board (TSB) and industry.
Funded through the UK Space Agency with the key aim to develop capabilities in future space instrumentation for Earth Observation through the teaming of scientists and industrialists.

Back to TIDAS…
TRL raising and system optimisation for an advanced thermal infrared imaging spectrometer for atmospheric science
It’s about combining high-resolution spectroscopy with a Fourier transform spectrometer with 2-D imaging at thermal IR wavelengths backed up by fast digital processing
There is not a single UK team that can tackle this alone… …Selex Galileo can create detector arrays & interface electronics …Astrium Ltd can do fast on-board signal processing
But neither is expert in Fourier Transform spectrometers nor in being able to bring science requirements into an overall system optimisation
