  1. 11. Integration and validation of a nanosatellite flight software (ESA OPS-SAT project)

    University essay from KTH/Rymdteknik

    Author : Anthony Surivet; [2021]
    Keywords : Flight software; On-board autonomy; Orbit control; Collision risks; Nanosatellite; Flygprogramvara; Inbyggd autonomi; Banreglering; Kollisionsrisker; Nanosatellit;

    Abstract : With the increasing number of satellites operating in orbit and the development of nanosatelliteconstellations, it has become more and more arduous for operators to keep track of every satellitestate, and perform corrective or avoidance manoeuvres. That is why CNES, the French space agency,is developing new algorithms, which aimed at making satellites more self-su cient. READ MORE

  3. 12. Stars Eating Planets

    University essay from Lunds universitet/Astronomi - Genomgår omorganisation

    Author : John Wimarsson; [2020]
    Keywords : Earth and planetary astrophysics; planetary dynamics; planet-planet scattering; planet consumption; Physics and Astronomy;

    Abstract : In a phase of instability during the dynamical evolution of some multiple exoplanetary systems, exchange of angular momentum and/or energy through gravitational interactions between planets will lead to alterations of their orbital properties. In some cases, planetary orbits end up crossing, which leads to close encounters between two planets. READ MORE

  4. 13. The I2T5 : Enhancement of the Thermal Design of an Iodine Cold Gas Thruster

    University essay from Luleå tekniska universitet/Rymdteknik

    Author : Roger Michael Pereira; [2020]
    Keywords : Cold gas thruster; I2T5; CubeSat propulsion; thermal analysis; heat transfer; thermal resistance; orbital heat fluxes;

    Abstract : The I2T5, an iodine-propelled, cold gas thruster, developed by ThrustMe, France, is the first of its kind to make it successfully to space. Due to its simple, reliable and cost-effective design, it is a suitable propulsion system for CubeSat missions with low delta-V (ΔV) requirements. READ MORE

  5. 14. High resolution imaging observations of exoplanet host stars

    University essay from Lunds universitet/Astronomi - Genomgår omorganisation

    Author : Kaltrina Kajtazi; [2020]
    Keywords : Speckle imaging; Speckle interferometry; High resolution imaging; Short integration time; Binaries; Exoplant hosts; Stellar properties; WIYN; Gemini; Orbital period; Physical separation; Angular separation; magnitude difference; Physics and Astronomy;

    Abstract : This is a thesis project, analysing data from high-resolution imaging observations, specifically speckle imaging, as a follow up study of exoplanet host stars observed with K2, the second operational phase of the space telescope Kepler. The project was accomplished at NASA Ames research center under the guidance of Rachel A. READ MORE

  6. 15. Skogsstyrelsens handläggning av avverknings-anmälningar : med hänsyn till renskötseln

    University essay from SLU/Dept. of Forest Resource Management

    Author : Maria Grånemo; [2019]
    Keywords : iRenmark; skogsstyrelsen; avverkningsanmälan; renskötsel; kvalitativ;

    Abstract : Skogsbruk och renskötsel bedrivs parallellt på en stor del av Sveriges skogsklädda yta. Skogsbruk bedrivs främst i form av trakthyggesbruk där bestånd planeras och sköts under en omloppstid på ungefär 100 år. Renskötseln bedrivs och planeras på landskapsnivå i förhållande till förutsättningarna ute i naturen. READ MORE
