1. 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
2. Attitude Dynamics and Control for the Task Scheduling of Agile Earth Observation Satellites
Master-uppsats, KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanikSammanfattning : This thesis deals with the scheduling problem for a constellation of Earth observation satellites, focusing on modelling the attitude dynamics to assess the tasking capabilities. A target selection algorithm is developed considering the time dependent manoeuvres between targets and the time-dependent value of the observed targets. LÄS MER
3. Resonance Mitigation in the Attitude Control of a Flexible Large Solar Sail
Master-uppsats, KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanikSammanfattning : This project is about the design process of a resonancemitigating algorithm for a large solar sail. The solar sail isa structure made up by four long booms in a cross patternwith suspended sails between the edges of the booms. Thespacecraft in this report is controlled using smaller rotatingsails at each tip of the booms. LÄS MER
4. Improving the safe mode robustness of an Earth observation satellite
Master-uppsats, KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanikSammanfattning : Airbus Defence and Space is developing an Earth observation platform. The payload of that platform is an optical instrument, which has to be protected from Sun dazzling in order to preserve its integrity. LÄS MER
5. Hardware-in-the-loop simulation and testing of the ADCS of the Beyond Atlas CubeSat
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : Beyond Atlas, a company based in Danderyd, Sweden is working on a Low Earth Orbit (LEO) 3U-CubeSat (Cube Satellite) exploration mission. As part of their maiden mission, they aim to validate the navigation, propulsion, and communication techniques of a CubeSat while it performs orbital maneuvers to collect photographs of space debris.
