1. 1. Design and Implementation of a Rocket Launcher Hybrid Navigation

   Master-uppsats, KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

   Författare :Omar Ugolini; [2023]
   Nyckelord :launch vehicle navigation; delayed Kalman filter; strapdown; navigering av bärraketer; fördröjt Kalman-filter; strapdown;

   Sammanfattning : Rocket Factory Augsburg (RFA) a German New Space Startup is developing a three-stage rocket launcher aiming at LEO/SSO orbits. A fundamental responsibility of the GNC team is the development of the rocket navigation algorithm to estimate the attitude, position, and velocity allowing the guidance and control loops to autonomously steer the rocket.

3. 2. Coordinate­Free Spacecraft Formation Control with Global Shape Convergence under Vision­Based Sensing

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

   Författare :Omid Mirzaeedodangeh; [2023]
   Nyckelord :Bispherical Coordinates; 3D Formation Control; Spacecraft Formation Flying; Multiagent Systems; Prescribed Performance Control; Vision-Based Sensing; Bisfäriska Koordinater; 3D Formationskontroll; Rymdfarkostformationsflygning; Multiagentsystem; Föreskriven Prestandakontroll; Synbaserad Avkänning;

   Sammanfattning : Formation control in multi-agent systems represents a groundbreaking intersection of various research fields with lots of emerging applications in various technologies. The realm of space exploration also can benefit significantly from formation control, facilitating a wide range of functions from astronomical observations, and climate monitoring to enhancing telecommunications, and on-orbit servicing and assembly.

4. 3. X-ray-induced intermolecular reactions in mixed clusters

   Kandidat-uppsats, Uppsala universitet/Institutionen för fysik och astronomi

   Författare :Astrid Bergman; [2022]
   Nyckelord :molecular cluster; biophysics; X-ray;

   Sammanfattning : The aim of this project was to study what mixed cluster fragments were formed in the interaction between radiation and H2O-CO2 clusters formed by adiabatic expansion, both experimentally and using simulations. The experiment was done using a mass spectrometer at the MAX IV synchrotron facility and by studying the time-of-flight of the ionic fragments. LÄS MER

5. 4. Risk computation for atmospheric re-entry

   Master-uppsats, KTH/Rymdteknik

   Författare :Florian Teilhard; [2021]
   Nyckelord :Spacecraft Dynamics; Atmospheric re-entry; Rymdfarkosters dynamik; Atmosfäriska återinträdet;

   Sammanfattning : In the present work, two numerical tools are under scrutiny. Both were made to study the atmospheric re-entry of a spacecraft: DEBRISK computes the trajectory and the survivability of the spacecraft as well as its fragments, and ELECTRA calculates the trajectory of the spacecraft and its fragments, as well as the associated on-ground risk of human casualty.

7. 5. Mission Planning for the in-orbit Lunar calibrations of the MicroCarb instrument

   Master-uppsats, KTH/Rymdteknik

   Författare :Erwan Caffier; [2021]
   Nyckelord :Phase angle; radiance; Moon; carbon monitoring; flight dynamics simulation; mission planning; Fasvinkel; radians; Månen; koldioxidövervakning; flygdynamik simulering; rymduppdragsplanering;

   Sammanfattning : In-orbit calibrations of space instruments are often necessary to ensure the accuracy of the measurements. The Moon provides a target with very predictable characteristics. LÄS MER
