About CHRIS

PROBA-1 CHRIS instrument

PROBA-1's main instrument is the Compact High Resolution Imaging Spectrometer (CHRIS), which has applications in atmosphere, land, agriculture and oceans and coast.

It acquires 13 square km scenes at 17 m spatial resolution in 18 user-selected visible and near-infrared wavelengths.

CHRIS was funded by the UK Space Agency (at the time the British National Space Centre (BNSC)) and Sira Electro-Optics Ltd, and developed/built by Sira Technology Ltd (formerly Sira Electro-Optics Ltd).
