  1. 1. Real Time Navigation Algorithms for LEO Small Satellites using COTS GNSS

    Master-uppsats, KTH/Lantmäteri – fastighetsvetenskap och geodesi

    Författare :Nathan Groisne; [2023]
    Nyckelord :PNT; Small Satellite; COTS; GNSS; Navigation; ACS; PNT; små satelliter; COTS; GNSS; navigering; ACS;

    Sammanfattning : Many satellites in LEO use a GNSS-based navigation system, taking advantage of the GNSS constellations in MEO to enhance navigation capabilities. The thesis work focused on developing the software enabling GNSS-based navigation for Hemeria's future small satellites operating in LEO. LÄS MER

  3. 2. Thermal environment and design considerations of the Foresail-2 satellite mission

    Master-uppsats, Luleå tekniska universitet/Rymdteknik

    Författare :Deepa Anantha Raman; [2023]
    Nyckelord :satellite; thermal control; radiation; heat transfer; boom;

    Sammanfattning : The thermal design of small satellite missions is critical for ensuring the performance and longevity of onboard instruments. This thesis focuses on the thermal design of Foresail-2, a 6U CubeSat mission to Geostationary Transfer Orbit (GTO), specifically addressing the thermal challenges associated with the magnetometer located at the end of a long boom featured on the satellite.

  4. 3. Radiation Shielding Simulations for Small Satellites on Geostationary Transfer Orbit

    Master-uppsats, Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Författare :Anton Fetzer; [2022]
    Nyckelord :GTO; Foresail-2; CubeSat; Radiation Shielding; Geant4; Radiation Belts; GTO; Foresail-2; CubeSat; säteilysuojaus; Geant4; säteilyvyöhyke;

    Sammanfattning : The emergence of small and affordable satellites has led to rapid growth in the number of launched satellites over the past two decades. To save costs, small satellites often use mass-produced electronic components not explicitly designed for the radiation environment of space, which reduces reliability and makes them unsuitable for higher orbits.

  5. 4. Small Satellite Design for High Sensitivity Magnetic Measurements

    Master-uppsats, Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Författare :Noel Sebastian Janes; [2022]
    Nyckelord :Magnetic Cleanliness; FORESAIL; CubeSats; High Sensitivity Magnetic Measurements; Small Satellite;

    Sammanfattning : The magnetic cleanliness of a spacecraft during magnetic measurements is an important aspect in the design of many space science missions. The adequate reduction or removal of the spacecraft's magnetic disturbance plays a vital role in allowing the ambient magnetic field to be measured with the required accuracy. LÄS MER

  7. 5. Multiple CubeSat Mission for Auroral Acceleration Region Studies

    Master-uppsats, Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Författare :Marley Santiago Castro; [2021]
    Nyckelord :formation flight; mission analysis; aurora; auroral acceleration region; AAR; matlab; mission design; cubesat; cube satellites; multiple spacecraft;

    Sammanfattning : The Auroral Acceleration Region (AAR) is a key region in understanding the interactionbetween the Magnetosphere and Ionosphere. To understand the physical, spatial, and temporal features of the region, multi-point measurements are required. LÄS MER
