This low cost Hyperspectral Sensor is delivering cutting-edge, multi-application, earth observation imagery to research groups around the world.
CHRIS hyperspectral images of Earth provide multi-angle views of each target in many different wavebands, enabling a variety of surface features to be analysed.
It has an expanding portfolio of uses, encompassing agricultural mapping, water quality monitoring, coastal watch, charting forest fire damage and disaster management.
Military applications include surveillance, target detection and identification using sub-pixel classification, and camouflage penetration.
Its compact, patented optics and unique geometric layout enable CHRIS to deliver superior images of the Earth's surface.
Mike Cutter, Business Director of the Space business unit comments, "Weighing less than 14kg and consuming a mere 8 Watts of power, CHRIS opens up high performance spectral imaging to 100kg satellites.
The diversity of applications continues to expand as we push back the boundaries of space imaging".
CHRIS is the main instrument on the European Space Agency (ESA) small satellite platform PROBA (Project for On-Board Autonomy), launched from the Indian PSLV on 22 October 2001.
PROBA agility compliments the unique capabilities of CHRIS, allowing images to be collected from multiple angles during a single pass to overcome the obstacles of cloud cover and the effects of sun glint from water.
With a resolution nearly twice that of previous hyperspectral imagers, CHRIS provides data that has never before been available.
Its remarkable capabilities have aroused interest worldwide.
At the end of April 2004, around 50 researchers met at the ESA European Space Research Institute (ESRIN) in Italy.
They heard how the International Charter on Space and Major Disasters planned to increase its use of CHRIS imagery for high-resolution damage assessment as a response tool during disaster situations.
