Minimize OLCI Instrument Payload

The SENTINEL-3 Ocean and Land Colour Instrument (OLCI) is based on the opto-mechanical and imaging design of ENVISAT's MERIS instrument. The main characteristics of the OLCI are:

  • swath width: 1 270 km
  • push-broom imaging spectrometer with five cameras, mitigation of sun-glint contamination by tilting cameras in westerly direction
  • spatial sampling: 300 m @ SSP
  • spectrum: 21 bands [0.4-1.02] ┬Ám
  • radiometric accuracy: 2% abs, 0.1% rel
  • launch mass: 153 kg
  • size: 1.3 m3
  • design lifetime: 7.5 years.
