    • A JPEG2000 Encoder Interpretation 

      Bø, Tore Våland (Master thesis, 2018)
      Students at the Norwegian University of Science and Technology (NTNU) are developing a CubeSat through the Orbit project. The on-board image compression system will be implemented on an FPGA. Continuing from previous work, ...

    • A study of hardware compression of images 

      Rønning, Per Arne (Master thesis, 2016)
      In this paper, we will take a closer look at the possibility of compressing images to the JPEG 2000 standard using an FPGA's hardware architecture. This FPGA will be put into a satellite, which is going to orbit the earth ...

    • Design of Waveguide Cavity Filters for Ku-band Satellite Applications 

      Gjersvik, Amund (Master thesis, 2007)
      In this master's thesis several waveguide cavity filters are designed and simulated and three of them are constructed, two third order and one fifth order filter. One third order filter is fabricated in brass, and the two ...

    • Development of a prototype of a candidate camera payload 

      Oltedal, Jon Kalevi (Master thesis, 2016)
      The second prototype for the NUTS camera module have been tested to confirm if changes made from the first prototype were successful. The first prototype suffered from noise issues when operating at the maximum clock ...

    • Experimental set-up of a thermal vacuum chamber for thermal model in-house correlation and characterization of the HYPSO hyperspectral imager 

      Navarro-Medina, Fermin; Oudijk, Adriënne Esmeralda; Henriksen, Marie Bøe; Gjersvik, Amund; Grønvold, Fredrik Sommerfelt; Johansen, Tor Arne (Peer reviewed; Journal article, 2023)
      Space environment with changing temperatures and vacuum can affect the performance of optics instruments onboard satellites. Thermal models and tests are typically done to understand the optics performance within large ...

    • Hardware in the Loop Testing of Explicit Model Predictive Control of The CubeSat Selfie-Sat 

      Mostad, Martin (Master thesis, 2019)
      To eksplisite Model Prediktive Kontrollere ble utviklet for CubeSaten Selfie-Sat. Den ene kontroller skulle bruke til å peke et kamera, mens den andre skulle bruke til å holde satellitten i en ideell orientasjon for lading. ...

    • Pre-Launch Assembly, Integration, and Testing Strategy of a Hyperspectral Imaging CubeSat, HYPSO-1 

      Prentice, Elizabeth; Honoré-Livermore, Evelyn; Bakken, Sivert; Henriksen, Marie Bøe; Birkeland, Roger; Hjertenæs, Martine Aasen; Gjersvik, Amund; Johansen, Tor Arne; Agelet, Fernando Aguado; Navarro-Medina, Fermin (Peer reviewed; Journal article, 2022)
      Assembly, Integration, and Verification/Testing (AIV or AIT) is a standardized guideline for projects to ensure consistency throughout spacecraft development phases. The goal of establishing such a guideline is to assist ...
