Minimize SLSTR Instrument Payload

Following ENVISAT's AATSR instrument, the SLSTR instrument is a conical scanning imaging radiometer employing the along track scanning dual view technique.

The main characteristics of the SLSTR are:

  • swath width: dual view scan, 1 420 km (nadir) / 750 km (backwards)
  • spatial sampling: 500 m (VIS, SWIR), 1 km (MWIR, TIR)
  • spectrum: nine bands [0.55-12] ┬Ám
  • noise equivalent dT: 50 mK (TIR) at 270 K
  • launch mass: 90 kg
  • size: 2.116 m3
  • design lifetime: 7.5 years.
