Attitude Determination and Control System Testbed for Hardware and Software Testing and Verification for Small Satellites
Olsen, Jørgen Anker (Master thesis, 2021)I de siste årene har det vært en økning av antall småsatellitter som har blitt laget og sendt ut i verdensrommet. En viktig del av den nødvendige teknologien for a få disse til å virke som de skal, er kontrollsystemer som ... -
A Constrained Control Allocation and Tuning Scheme for Hybrid Actuators in Spacecraft Attitude Control
Grøtte, Mariusz Eivind; Gravdahl, Jan Tommy; Johansen, Tor Arne (Peer reviewed; Journal article, 2023)Agile rotational maneuvers of spacecraft requires careful execution since its actuators may not be able to produce the demanded torques, causing the state trajectories to deviate and a desired attitude would not be guaranteed. ... -
Design space exploration for hyperspectral image processing pipeline in HYPSO mission
Døsvik, Kristine (Master thesis, 2022)HYPSO er et NTNU forskningsprosjekt som har som mål å oppdage giftige algeoppblomstringer i havet. HYPSO bruker hyperspektral avbildning fra verdensrommet for å få informasjon om algeoppblomstringen. Tanken er at oppdrettsanlegg ... -
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 ... -
Simulation tool for hyper-spectral imaging from a satellite
Lapadatu, Monica; Bakken, Sivert; Grøtte, Mariusz Eivind; Alver, Morten; Johansen, Tor Arne (Journal article; Peer reviewed, 2019)This paper presents a tool created for simulating the expected radiance from oceanic geophysical parameters through the atmosphere as perceived by a hyperspectral remote sensing satellite. The effects of varying off-nadir ... -
Spacecraft Attitude and Angular Rate Tracking using Reaction Wheels and Magnetorquers
Grøtte, Mariusz Eivind; Gravdahl, Jan Tommy; Johansen, Tor Arne; Larsen, Jesper A; Vidal, Edgar M; Surma, Egidijus (Peer reviewed; Journal article, 2020)Spacecraft remote sensing applications may require slew maneuvers that prioritize small ground track errors during imaging, low power consumption and quick settling time. This paper investigates attitude control with a ...
