  1. 11. Development of a Low Earth Orbit Mission Preliminary Analysis Tool

    Master-uppsats, KTH/Rymdteknik

    Författare :Giada Staniscia; [2019]
    Nyckelord :Mission analysis; CubeSat; Propulsion; Low Earth Orbit LEO ; Perturbations; Atmospheric drag; Earth oblateness.;

    Sammanfattning : The objective of this project is the development of a mission analysis tool for the nanosatellite company GomSpace Sweden. Although there are many existing software, they can be quite complicated and time consuming to use. LÄS MER

  3. 12. A feasibility study for a satellite VHF Data Exchange System (VDES)

    Master-uppsats, KTH/Rymdteknik

    Författare :Julian Grujicic; [2019]
    Nyckelord :Systems engineering; satellite design; satellite communication; AIS; VDES; LEO; satellite constellation; CubeSat; new space .; Systemteknik; satellitdesign; satellitkommunikation; AIS; VDES; Låg-jordbana; satellitkonstellation; CubeSat .;

    Sammanfattning : Transportation across the globe's oceans increases every year and is expected to keep increasing in the following decades. Consequently, there is a need to establish communication over the horizon through the Automatic Identification System (AIS) and the Very High Frequency (VHF) Data Exchange System (VDES), still in development, to track and communicate with vessels all over the globe regardless of the distance from shore.

  4. 13. Laser Orbital Derbis Removal : Studies of Spacecraft Debris Removal Using Ground Based Lasers

    Master-uppsats, Luleå tekniska universitet/Rymdteknik

    Författare :Kajsa Eriksson Rosenkvist; [2019]
    Nyckelord :Laser; Orbital; Debris; Removal;

    Sammanfattning : Overcrowding of the Low Earth Orbit (LEO) region is a growing problem. Decades of treating this part of space like a scrap yard has caused it to become a hazardous environment for operating satellites. LÄS MER

  5. 14. A Thermal Investigation and Comparative Study of the Foresail Missions

    Master-uppsats, Luleå tekniska universitet/Rymdteknik

    Författare :Kartik Naik; [2019]
    Nyckelord :Thermal; Space; CubeSat; Cube Satellite;

    Sammanfattning : Cube Satellite (CubeSat) launches have been on the rise since its first launch in2003. This popularity is mainly due to faster design process and lower launch costs.However, most CubeSats are launched into Low Earth Orbits (LEOs), with nomissions to Geostationary Transfer Orbits (GTOs). However, many mission areplanned for the next half-decade. LÄS MER

  7. 15. Konceptuell flygplansdesign : Design av flygplan för luft lanserad satellit

    Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)

    Författare :Aaron Poutiainen; Fei Von Sivers; [2018]
    Nyckelord :;

    Sammanfattning : Det här kandidatexamensarbetet handlar om att design ett flygplan för raketavfyrning på hög höjd. Raketen ska bära satelliten PICARD som väger 143 kg och ska skjutas upp i omloppsbana runt jorden. Flygplanets nyttolast, raketens massa, är tre ton. LÄS MER
