  1. 1. PPS5000 Thruster Emulator Architecture Development & Hardware Design

    Master-uppsats, Luleå tekniska universitet/Rymdteknik

    Författare :Robert Persson; [2019]
    Nyckelord :Electric Propulsion; Spacecraft; Ground Support Equipment; OHB Sweden; Emulator; Thruster; Elektrisk Framdrivning; Rymdfarkost; Markutrustning; Testutrustning;

    Sammanfattning : This Master's Thesis handles prestudy work and early hardware development that resulted in architectural definitions and prototype hardware of electronic ground support equipment. This equipment is destined to emulate the electric power consumption of the PPS5000 Hall Effect Thruster (HET), for use in satellite end-to-end tests of the all-electric Geostationary Satellite Electra, developed at OHB Sweden AB.

  2. 2. Dynamic Analysis of Sinusoidal, Random and Shock Vibration according to Launch Environment for Small Spacecraft Development to Asteroid 2016-HO3

    Master-uppsats, KTH/Lättkonstruktioner

    Författare :Akhsanto Anandito; [2019]
    Nyckelord :spacecraft; resonance frequency; sinusoidal; random vibration; shock; FEM; rymdfarkoster; resonansfrekvens; sinusformad; slumpmässig vibration; chock; FEM;

    Sammanfattning : The investment of space commerce is skyrocketing and it is predicted to be a nascent business in the future. The spacecraft demand has been growing not only for NASA and other space agency’s mission but also collaboration business between small space industries, academia, and scientific community. LÄS MER

  3. 3. "Så träffades vi likafullt av spjutet" - En existentialistisk läsning av Harry Martinsons rymdepos Aniara. En revy om Människan i Tid och Rum

    Kandidat-uppsats, Göteborgs universitet/Institutionen för filosofi, lingvistik och vetenskapsteori

    Författare :Alicia Lindström; [2018-08-15]
    Nyckelord :Aniara; Existentialism; Martinson; Harry Martinson;

    Sammanfattning : Harry Martinsons berömda rymdepos Aniara. En revy om människan i tid och rum (1956) beskriverhur en grupp människor är lämnade åt sitt öde när deras rymdfarkost, tänkt att ta dem till Mars, hamnar ur kurs och far planlöst ut i kosmos. LÄS MER

  4. 4. Combined Attitude and Orbital MPC for Thruster Based Spacecrafts

    Master-uppsats, KTH/Reglerteknik

    Författare :Joakim Lilja; [2017]
    Nyckelord :;

    Sammanfattning : A spacecraft needs to simultaneously provide orbital and attitude controlbut these are in general treated as separate systems. Normally the attitudecontrol is conducted via reaction wheels but can in scenarios with high manoeuvrabilitydemands be handed over to pure thruster control. LÄS MER

  5. 5. A Method for Standardization within the Payload Interface Definition of a Service-Oriented Spacecraft using a Modified Interface Control Document​

    Master-uppsats, KTH/Rymdteknik

    Författare :Laura Klicker; [2017]
    Nyckelord :Astrobotic Technologies; Commercialization of Space; Interface Control Document; Interface Definition; Interface Management; Peregrine Lunar Lander; Service-Oriented Space Program; Space Exploration; Space Systems Engineering; Standardization;

    Sammanfattning : With a big picture view of increasing the accessibility of space, standardization is applied within a service-oriented space program. The development of standardized spacecraft interfaces for numerous and varied payloads is examined through the lens of the creation of an Interface Control Document (ICD) within the Peregrine Lunar Lander project of Astrobotic Technologies, Inc.
