  1. 1. Testing for verification and validation of an onboard orbit determination system exploiting GNSS : A nanosatellite application for HERMES-SP

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Clara Nermark; [2023]
    Nyckelord :Onboard orbit determination system; GNSS; nanosatellite; testing; verification and validation; Ombord banbestämning; GNSS; nanosatellit; testning; verifikation och validering;

    Sammanfattning : When developing products for space, including nanosatellites, the verification and validation process is a mandatory part of any project conducted within the European space industry. Within such a process, testing is a method for verification and validation. LÄS MER

  3. 2. Investigations of the Transient Luminous Events with the small satellites, balloons and ground-based instruments

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

    Författare :Safura Mirzayeva; [2022]
    Nyckelord :TLE; sprite; jet; elve; halo; lightning; lighting detection; upper-atmospheric lightning; lightning location; nanosatellite; CubeSat;

    Sammanfattning : The lightning is the natural source of electromagnetic radiation. It is an atmospheric electrical discharge.  However, since recent times, it was discovered that there are other types of lightning besides those that are visible to the naked eye. They are called TLEs (Transient Luminous Event) and take place above the clouds during thunderstorms. LÄS MER

  4. 3. Finite Element Analysis of Stresses in the MIST CubeSat due to Dynamic Loads During Launch

    Master-uppsats, KTH/Lättkonstruktioner

    Författare :Carl Järmyr Eriksson; [2021]
    Nyckelord :Satellite; CubeSat; Nanosatellite; Dynamic Loads; Launch Loads; Finite Element Analysis; FEA; Quasi-static Acceleration; Modal Analysis; Random Vibration; Shock Loads; satellit; CubeSat; nanosatellit; dynamiska laster; uppskjutningslaster; finita elementmetoden; FEM; kvasistatisk acceleration; modalanalys; stokastiska vibrationer; chocklaster;

    Sammanfattning : A finite element model of the CubeSat MIST was created, in order to assess the stresses that occur in the satellite in response to loads during its launch. Due to size limits of thesoftware used, simplifications had to be made to the geometry of the model. LÄS MER

  5. 4. Modelling And Simulation of Attitude AndOrbital Control For Foresail-2

    Master-uppsats, Luleå tekniska universitet/Rymdteknik

    Författare :Tushar Sharma; [2021]
    Nyckelord :;

    Sammanfattning : A central factor affecting spacecraft lifetime is the radiation environment, which isunpredictable due to an incomplete understanding of plasma dynamics. FORESAIL2 will build on the FORESAIL-1 results – measurements of radiation belt lossesand demonstrate deorbiting in LEO. LÄS MER

  7. 5. Design and Development of the Space Campus Ground Station for Small Satellites

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

    Författare :Martin Elfvelin; [2021]
    Nyckelord :Ground Station; Telecommunication; Small Satellites; Space Communication;

    Sammanfattning : With the launch of the first CubeSat a trend of easy access to Low Earth Orbit was started. Today many educational institutes around the world design, build and operate CubeSats for educational as well as scientific purposes. LÄS MER
