DESIS  

Definition

  • The DLR Earth Sensing Imaging Spectrometer (DESIS) is an Earth observation instrument that was launched to the International Space Station (ISS) in 2018 and is integrated into the Multi-User System for Earth Sensing (MUSES) platform. DESIS is a pushbroom imaging hyperspectral sensor system with 235 hyperspectral narrowbands (HNB) each with 2.55 nm bandwidth that record image data from the visible and near-infrared (VNIR) range of the spectrum (400 to 1000 nm). It has a surface spatial resolution of about 30 meters and a swath width of about 30 km. DESIS is also equipped with a steering mirror for Bidirectional Reflectance Distribution Function (BRDF) measurements. This data reveals changes in the ecosystems on Earth's surface. Scientists can use the information acquired in this way to assess the condition of forests or farmlands and forecast their yield. DESIS was developed and built by the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) and is operated commercially by Teledyne Brown Engineering (TBE). (en)
