    • 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 ...

    • Energy and time optimal spacecraft attitude control and operations 

      Kristiansen, Bjørn Andreas (Doctoral theses at NTNU;2023:439, Doctoral thesis, 2023)
      In this thesis, we present a cost function based on net power as a way to make attitude control maneuvers energy optimal for solar-powered spacecraft. Previous work has defined energy optimality in terms of input norms or, ...

    • Energy Optimal Attitude Control and Task Execution for a Solar-Powered Spacecraft 

      Kristiansen, Bjørn Andreas; Gravdahl, Jan Tommy; Gros, Sebastien Nicolas; Johansen, Tor Arne (Peer reviewed; Journal article, 2024)
      In this article, we aim to maximize the net energy a solar-powered spacecraft gains when performing a sequence of tasks leading to attitude maneuvers over the spacecraft’s orbit, including an eclipse. The net energy can ...

    • 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 ...

    • Maximum Hands-Off Attitude Control 

      Schaanning, Sigrid Kjønnø; Kristiansen, Bjørn Andreas; Gravdahl, Jan Tommy (Peer reviewed; Journal article, 2022)
      In this paper, we explore the use of maximum hands-off control for attitude control of a spacecraft actuated by reaction wheels. The maximum hands-off, or L 0 -optimal, controller aims to find the sparsest control signal ...

    • Maximum Hands-Off Attitude Control of a Spacecraft Actuated by Thrusters 

      Kristiansen, Bjørn Andreas; Gravdahl, Jan Tommy (Journal article; Peer reviewed, 2023)
      In this paper we investigate the use of maximum hands-of control for spacecraft attitude control of a spacecraft equipped with thrusters. Other than a more natural choice of actuators than in our previous paper, the ...

    • Maximum Hands-Off Control for Attitude Control of a Spacecraft 

      Schaanning, Sigrid Kjønnø (Master thesis, 2021)
      Denne avhandlingen utforsker bruken av "maximum hands-off" regulering for attituderegulering av en satellitt som er drevet av reaksjonshjul. Maximum hands-off, eller den L0-optimale, regulatoren forsøker å finne pådragssignalet ...

    • Nonlinear Attitude Control of a Pointing and Slewing Spacecraft 

      Kristiansen, Bjørn Andreas (Master thesis, 2019)
      Dynamikken i en satellitts bane og attitude modelleres for en satellitt med reaksjon- shjul og magnetorquere som aktuatorer. Den ulineære modellen er implementert i Matlab/Simulink. Regulatorene som blir brukt er konvensjonell ...

    • Quaternion-Based Generalized Super-Twisting Algorithm for Spacecraft Attitude Control 

      Kristiansen, Bjørn Andreas; Grøtte, Mariusz Eivind; Gravdahl, Jan Tommy (Peer reviewed; Journal article, 2020)
      A second-order sliding mode control, the generalized super-twisting algorithm (GSTA), is used for attitude control of a spacecraft actuated by reaction wheels for pointing and a slewing maneuver. Magnetorquers are used for ...
