11. Design of the control system for a powered landing maneuver of a rocket
Master-uppsats, Luleå tekniska universitet/RymdteknikSammanfattning : The powered soft landing of a spacecraft represents a maneuver with high interest, withsome private launcher companies – SpaceX, Blue Origin, Rocket Factory Augsburg, etc. - showinginterest in implementing it as a solution for their launchers, and several national agenciesusing it for the exploration of celestial bodies where it may be the only option.

12. Volumetric Rendering of the Inner Coma of a Theoretically Modelled Comet for Comet Interceptor Mission
Master-uppsats, Luleå tekniska universitet/RymdteknikSammanfattning : The Comet Interceptor is a joint mission by European Space Agency (ESA) and Japan Aerospace Exploration Agency (JAXA) which seeks to perform a flyby over a Long Period Comet using a multi-element spacecraft. The Comet Interceptor comprises three spacecrafts- A, B1 and B2. LÄS MER
13. Electromagnetic Compatibility (EMC) test in an Open Area
Master-uppsats, Luleå tekniska universitet/RymdteknikSammanfattning : Electromagnetic compatibility (EMC) is a very important and increasingly relevant technology in use and is closely related to many technologies such as automobiles and aerospace industry technology including aircraft and spacecraft. Achieving electromagnetic compatibility between equipment inside the device is more than necessary to avoid the problem of interference leading to serious problems. LÄS MER
14. WSA-ENLIL + Cone ensemble modeling of an Earth-directed ICME : Comparison with in-situ observations by Solar Orbiter and WIND at L1
Master-uppsats, Uppsala universitet/Institutionen för fysik och astronomi; Uppsala universitet/Institutet för rymdfysik, UppsalaavdelningenSammanfattning : Coronal mass ejections (CMEs) are considered the most energetic phenomenon in the heliosphere. Originated in the solar corona, they are formed by ejected plasma driven by strong magnetic fields. LÄS MER
15. Real Time Navigation Algorithms for LEO Small Satellites using COTS GNSS
Master-uppsats, KTH/Lantmäteri – fastighetsvetenskap och geodesiSammanfattning : 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
