Technical Information:
Instrument : Compact High Resolution Imaging Spectrometer (CHRIS)
Date of Acquisition : 15-04-2002
Instrument Features : 3 bands (466nm, 543nm, 641nm) image, 15 m spatial resolution, 768x1010 pixels


 
Konakri, Guinea, seen from PROBA-1’s CHRIS instrument.

The Project for On-Board Autonomy (Proba) is a technology demonstration mission of the European Space Agency.

CHRIS is a push-broom spectrometer capable of imaging up to 200 spectral bands in the visible range. Together with the scanning and manoeuvring capabilities of the spacecraft it supports Bidirectional Reflectance Distribution Function (BRDF) measurements used in land, sea and atmospheric observations.
