1. Planet-NeRF : Neural Radiance Fields for 3D Reconstruction on Satellite Imagery in Season Changing Environments
Master-uppsats, Linköpings universitet/DatorseendeSammanfattning : This thesis investigates the seasonal predictive capabilities of Neural Radiance Fields (NeRF) applied to satellite images. Focusing on the utilization of satellite data, the study explores how Sat-NeRF, a novel approach in computer vision, per- forms in predicting seasonal variations across different months. LÄS MER
2. Investigation of Antenna Radomes in Low Earth Orbits
Master-uppsats, Lunds universitet/Centrum för analys och syntesSammanfattning : Introduction: This master’s thesis focuses on exploring improved alternative material solutions for antenna radomes used to protect Beyond Gravity Sweden’s satellite antennas in low Earth orbits. Background: As the environment in low Earth orbit is harsh, surface materials on satellites experience high levels of atomic oxygen, ultra violet radiation, thermal-fluctuation, charged particles and micro meteoroids.

3. Using forest reflectance modelling to estimate albedo for narrow-view satellites
Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap; Lunds universitet/Fysiska institutionenSammanfattning : Surface albedo estimations from remote sensing are invaluable for energy balance descrip- tions in climate research. The aim of this work is to evaluate the possibility of using Sentinel-2 satellite data to get the total albedo of a small, vegetated area. LÄS MER
4. Estimating stellar limb darkening using exoplanet transits
Kandidat-uppsats, Lunds universitet/Astrofysik; Lunds universitet/Fysiska institutionenSammanfattning : The brightness of the stars is not uniform over the surface as it varies depending on the wavelength and the atmosphere that the light propagates. Limb darkening is an optical effect caused by a decrease in brightness of the star towards the edge. LÄS MER
5. Hardware-In-the-Loop Simulation of MIST Attitude Determination and Control System
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : The MIST(MIniature Student saTellite) project is a 3U CubeSat developed by student teams at KTH Royal Institute of Technology in Stockholm. One of the fundamental systems of the satellite is the Attitude Determination and Control System (ADCS), re sponsible for estimating and correcting the satellite’s orientation using magnetic fields and sun sensors.
