   Författare :Likitha Thimmaraju Girijadevi; [2023]
   Nyckelord :6U CubeSat; Propulsion system; Vibration testing; COMSOL; Structures; ECSS; Stress; Resonance; Frequency; Load; Simulation.; 6U CubeSat; Framdrivningssystem; Vibrationstestning; COMSOL; Strukturer; ECSS; Stress; Resonans; Frekvens; Belastning; Simulering.;

   Sammanfattning : Space industry has been booming in the recent times, investments have not justbeen made on satellites and launch vehicles but also on space sustainability. Spaceindustry has its users in national agencies, private commercial agencies, academia andexperimental organisations. LÄS MER

3. 2. Development of Operations Complement to the Space System Ontology

   Master-uppsats, Luleå tekniska universitet/Rymdteknik

   Författare :Kiira Tiensuu; [2022]
   Nyckelord :space systems engineering; model-based systems engineering;

   Sammanfattning : Space system development is a complex process that typically involves multiple stakeholders. Traditionally, information is captured and exchanged in the form of documents. Efficient exchange of information is crucial, but often challenging with the traditional document-based approach and multitude of stakeholders. LÄS MER

4. 3. Using Enterprise Collaboration Systems During a Pandemic : What factors influence the value derived from the push to working through Enterprise Collaboration Systems during the Covid-19 pandemic? 

   Master-uppsats, Linnéuniversitetet/Institutionen för informatik (IK)

   Författare :Nicklas Joar Brundin; [2021]
   Nyckelord :Enterprise Collaboration System; ECS; Covid-19; Pandemic; Service-Dominant Logic; Work From Home; Remote Work; Mixed Method; Hybrid;

   Sammanfattning : Why do individuals derive different value when working remotely using Enterprise Collaboration Systems during Covid-19? This mixed methodology research used a Service-Dominant Logic lens and undertook a literature review, qualitative interviews and a quantitative survey to identify the characteristics and variables that impacted perceived value for individual Australian Actors. To assist future studies it also developed an equivalency model of value and the desire to work remotely. LÄS MER

5. 4. Error Injection Study for a SpaceFibre In-Orbit Demonstrator

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

   Författare :Carlos Abad Garcia; [2020]
   Nyckelord :;

   Sammanfattning : The space electronics sector is shifting towards the New-Space paradigm, in which traditional space-quali_ed and expensive components and payloads are replaced by commercial o_-the-shelf (COTS) alternatives. This change in mentality is accompanied by the development of inexpensive cubesats, lowering the entry barrie in terms of cost, enabling an increase in scienti_c research in space. LÄS MER

7. 5. FORESAIL-2 AOCS Trade Studies and Design

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

   Författare :Guillaume Le Bonhomme; [2020]
   Nyckelord :space engineering; CubeSat; ADCS; AOCS; spacecraft subystems; nanosatellite;

   Sammanfattning : This thesis aims to design a reliable CubeSat platform, including the avionic subsystems that can sustain a high radiation environment for a mission having a lifetime of at least six months. The science instruments put stringent requirements on the platform to achieve and maintain the desired spin rate. LÄS MER
