1. 1. Real Time Navigation Algorithms for LEO Small Satellites using COTS GNSS

   Master-uppsats, KTH/Lantmäteri – fastighetsvetenskap och geodesi

   Författare :Nathan Groisne; [2023]
   Nyckelord :PNT; Small Satellite; COTS; GNSS; Navigation; ACS; PNT; små satelliter; COTS; GNSS; navigering; ACS;

   Sammanfattning : Many satellites in LEO use a GNSS-based navigation system, taking advantage of the GNSS constellations in MEO to enhance navigation capabilities. The thesis work focused on developing the software enabling GNSS-based navigation for Hemeria's future small satellites operating in LEO. LÄS MER

3. 2. Improving Dependability of Space-Cloud Payload Processor by Storage System

   Master-uppsats, Mälardalens universitet/Akademin för innovation, design och teknik

   Författare :Hassan Said; Stephanie Liza Johansson; [2023]
   Nyckelord :Fault tolerant; Markov analysis; Onboard processing; SSD array architecture; SSD; EDAC; RAID; Hamming code; Reed Solomon; Dependability evaluation; File systems; ZFS; Ext4.;

   Sammanfattning : Due to the usage of complicated platforms and current high-performance space computing technology, onboard processing in small satellites is expanding. Space-cloud payload processors with Commercial Off-The-Shelf (COTS) components, that are required to be radiation-tolerant, are used to perform the onboard processing. LÄS MER

4. 3. Attitude Determination and Control System of a CubeSat in Suborbital Flight

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

   Författare :Joan Jordi Boldu O Farrill Treviño; [2020]
   Nyckelord :;

   Sammanfattning : The Bistable Boom Dynamic Deployment (B2D2) experiment aims to successfully demonstrate the deployment of a 2 meter self-deployable boom in order to offer an efficient alternative for small satellites to conduct higher quality magnetic field measurements. The boom will be placed in a free falling unit, following the CubeSat standard. LÄS MER

5. 4. Methods for Estimating the Magnetic Dipole Moment of Small Objects

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

   Författare :Elina Arvidsson; Rickard Brunskog; [2020]
   Nyckelord :MIST; student satellite; CubeSat; magneticdipole moment; magnetometer;

   Sammanfattning : A small satellite can be adversely affected by Earth’s magnetic field due to the resulting torque the magnetic field exerts on the satellites magnetic dipole moment. Therefore, this dipole moment needs to be estimated during the development of the satellite to make sure that the torque does not become a problem once the satellite is in orbit. LÄS MER

7. 5. Space Transportation and Exploitation Missions offered by the VEGA Transportation System that could reshape the European Space Industry

   Master-uppsats, KTH/Farkost och flyg

   Författare :Adrian Buzdugan; [2019]
   Nyckelord :Index Terms—AVIO; VEGA; VTS; VSS; Requirements; Kit approach; Modularity; Mission; Services; Space; Europe.;

   Sammanfattning : The aim of the thesis is to provide the mission requirements for the VEGA Transportation System(VTS), the equivalent of Phase 0 of a space project. The decrease in sizes and masses of the satellites opened the opportunity for the light capability VEGA launchers to contribute and reshape the European space value chain. LÄS MER
