    • Accuracy of a slew maneuver for the HYPSO-1 hyperspectral imaging satellite — in-orbit results 

      Kristiansen, Bjørn Andreas; Langer, Dennis David; Garrett, Joseph Landon; Berg, Simen; Gravdahl, Jan Tommy; Johansen, Tor Arne (Peer reviewed; Journal article, 2023)
      In this paper, the accuracy of a slew maneuver performed by the HYPSO-1 satellite is analysed based on the data received during the satellite’s first months in orbit. The slew maneuver, during which the satellite turns ...

    • Dimensionality reduction of hyperspectral images using an ICA-based stochastic second-order optimization algorithm 

      Lupu, Daniela; Necoara, Ion; Ionescu, Tudor C.; Ghinea, L M; Garrett, Joseph Landon; Johansen, Tor Arne (Chapter, 2023)
      Hyperspectral imaging is one of the advanced remote sensing techniques whose goal is to obtain the spectrum for each pixel in the image of a scene, with the purpose of finding objects, identifying materials or detecting ...

    • Ground systems software for automatic operation of the HYPSO-2 hyperspectral imaging satellite 

      Berg, Simen; Bakken, Sivert; Birkeland, Roger; Chiatante, Corrado; Garrett, Joseph Landon; Johansen, Tor Arne (Chapter, 2023)
      HYPSO-1 was launched in January 2022, equipped with a novel hyperspectral imaging payload with the main objective of performing marine research. In 2024, HYPSO-2, with an enhanced capture capacity, will be launched. The ...

    • Hyperspectral Imager Calibration and Image Correction 

      Henriksen, Marie Bøe (Master thesis, 2019)
      Hyperspektrale kameraer, ombord blant annet droner og småsatellitter, skal detektere algeoppblomstring og andre havfenomener langs norskekysten. Dette er en del av prosjektet HYPSO, som står for "hyperspektral småsatellitt ...

    • HYPSO-1 CubeSat: First Images and In-Orbit Characterization 

      Bakken, Sivert; Henriksen, Marie Bøe; Birkeland, Roger; Langer, Dennis David; Oudijk, Adriënne Esmeralda; Berg, Simen; Pursley, Yeshi; Garrett, Joseph Landon; Gran-Jansen, Fredrik; Honoré-Livermore, Evelyn; Grøtte, Mariusz Eivind Santora; Kristiansen, Bjørn Andreas; Orlandic, Milica; Gader, Paul; Sørensen, Asgeir Johan; Sigernes, Fred; Johnsen, Geir; Johansen, Tor Arne (Peer reviewed; Journal article, 2023)
      The HYPSO-1 satellite, a 6U CubeSat carrying a hyperspectral imager, was launched on 13 January 2022, with the Goal of imaging ocean color in support of marine research. This article describes the development and current ...

    • Independent component analysis: A tool for algal bloom detection 

      Penne, Cameron Louis; Garrett, Joseph Landon; Johansen, Tor Arne; Orlandic, Milica; Heggebø, Ragna (Peer reviewed; Journal article, 2023)
      Independent component analysis decomposition of hyperspectral signals has characteristics ideal for detecting harmful algal blooms in coastal waters. In this proceeding, independent component analysis is used to process ...

    • Monitoring Algal Blooms with Complementary Sensors on Multiple Spatial and Temporal Scales 

      Williamson, David Roddan; Moreira Fragoso, Glaucia; Majaneva, Sanna Kristiina; Dallolio, Alberto; Halvorsen, Daniel Ørnes; Hasler, Oliver Kevin; Oudijk, Adriënne Esmeralda; Langer, Dennis David; Johansen, Tor Arne; Johnsen, Geir; Stahl, Annette; Ludvigsen, Martin; Garrett, Joseph Landon (Peer reviewed; Journal article, 2023)

      The Norwegian University of Science and Technology (NTNU) has been building a system composed of multiple remote sensing agents for ocean observations. NTNU launched the first HYPerspectral Smallsat for Ocean observation ...

    • Robust and Reconfigurable On-Board Processing for a Hyperspectral Imaging Small Satellite 

      Langer, Dennis David; Orlandic, Milica; Bakken, Sivert; Birkeland, Roger; Garrett, Joseph Landon; Johansen, Tor Arne; Sørensen, Asgeir Johan (Peer reviewed; Journal article, 2023)
      Hyperspectral imaging is a powerful remote sensing technology, but its use in space is limited by the large volume of data it produces, which leads to a downlink bottleneck. Therefore, most payloads to date have been ...

    • Spatial Resolution Enhancement of Hyperspectral Images from Miniaturized Sensors
