  1. 1. Flight Dynamics Software Industrialisation for Inclined Orbits

    University essay from KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

    Author : Pierrick Houede; [2023]
    Keywords : flight; dynamics; software; FDS; geostationary; orbit; station; keeping; uncontrolled; inclination.;

    Abstract : The geostationary orbit has many applications for Earth observation and telecommunications. Like all satellites, spacecraft in this type of orbit are affected by perturbations. These perturbations can modify the satellites trajectories and, without control, deviate them from their target position. READ MORE

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

    University essay from Luleå tekniska universitet/Rymdteknik

    Author : Deepa Anantha Raman; [2023]
    Keywords : satellite; thermal control; radiation; heat transfer; boom;

    Abstract : 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

    University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

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

    Abstract : 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. Attitude control using ion thrusters for solar sailing from Low Earth Orbit to sub-L1

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : Celeste Holm; Ida Ygland; [2022]
    Keywords : the sunshade project; geoengineering; solar sailing; attitude control; ion thrusters;

    Abstract : The purpose of the study is to evaluate the possibility of using gridded ion thrusters as a means of attitude control for a solar sail as a part of the sunshade project, which aims to place 10^8 solar sail sunshade spacecraft, each with an area of about 10 000 m^2, at the Sun-Earth Lagrangian point L1 in order to reduce Earth's global temperature. Two types of solar sail sunshade spacecraft were studied. READ MORE

  6. 5. Design of a Satellite Constellation Intended for Use with a Small User Terminal

    University essay from KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

    Author : Mathias Axelsson; [2022]
    Keywords : ;

    Abstract : Satellite constellations intended for communications services are becoming increasingly relevant with multiple companies such as Starlink and OneWeb launching constellations consisting of hundreds or thousands of satellites. This thesis investigated how such a constellation can be designed for a small user terminal with a diameter of approximately 15 cm. READ MORE
