1. Space Rider System: GNC and System Model Improvements
Master-uppsats, KTH/RymdteknikSammanfattning : As part of a continuous trend of the space sector for obtaining higher performance space science and Earth observations, there is an increasing demand for higher requirements in pointing accuracy and disturbance prediction. The Space Rider System (SRS) is a Low Earth Orbit (LEO) reusable vehicle that aims at answering to that demand. LÄS MER
2. Forward Modelling of Ground Based SST Telescope Images
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : Space debris is becoming an increased threat to the future use of space orbits. In order to counteract this threat, the field of Space Situational Awareness (SSA), and the sub-field Space Surveillance and Tracking (SST), have been developed to gather knowledge about the space debris and satellites surrounding Earth.

3. Seeing Stars - Intensity Interferometry in the Laboratory and on the Ground
Master-uppsats, Lunds universitet/Astronomi - Genomgår omorganisationSammanfattning : Context Since the time of Tycho Brahe astronomy has been an observing science defined by the quality of its instrumentation. The introduction of primitive telescopes by Galileo in 1609 began a period of development of ever-larger telescopes with greater measuring precision. LÄS MER
4. Development and testing of algorithms for optimal thruster command distribution during MTG orbital manoeuvres
Master-uppsats, Luleå tekniska universitet/RymdteknikSammanfattning : An accurate satellite attitude and orbit control is a key factor for a successful mission. It guarantees for example sun acquisition on solar panels, fine pointing for optimal telescope usage or satellite lifting to reach higher orbits, when required. LÄS MER
5. Methods for Estimating the Magnetic Dipole Moment of Small Objects
Kandidat-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)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
