  1. 1. Starshades: Geoengineering Solutions and Technosignatures in Direct Imaging Phase Curves

    University essay from Lunds universitet/Astrofysik; Lunds universitet/Fysiska institutionen

    Author : Claudia Skoglund; [2023]
    Keywords : Starshades; extraterrestrial intelligence; stellar evolution; technosignatures; phase curves; direct imaging; habitable zone.; Physics and Astronomy;

    Abstract : The stellar luminosity increases as a star evolves which inevitably yields a higher temperature on planets in orbit around the star. It is reasonable to assume that intelligent civilizations would tackle this issue through installing artificial structures that can alter the radiation received by the planet. READ MORE

  3. 2. Initial Orbit Determination of Resident Space Objects From A Passive Optical Imaging System: : Application to Space Situational Awareness

    University essay from Luleå tekniska universitet/Rymdteknik

    Author : Jessica McKenna; [2023]
    Keywords : Space Situational Awareness; Space Science; Angles-Only Initial Orbit Determination;

    Abstract : The probability of satellite collisions and disintegrations cluttering the near-Earth orbital environmentis ever-growing. This is especially true for the congested Low Earth Orbit (LEO) regime; once a critical density of objects is reached, a collisional cascading is projected to generate runaway growth of theorbital population.

  4. 3. Using Machine Learning to Optimize Near-Earth Object Sighting Data at the Golden Ears Observatory

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Laura Murphy; [2023]
    Keywords : Near-Earth Object Detection; Machine Learning; Deep Learning; Visual Transformers;

    Abstract : This research project focuses on improving Near-Earth Object (NEO) detection using advanced machine learning techniques, particularly Vision Transformers (ViTs). The study addresses challenges such as noise, limited data, and class imbalance. READ MORE

  5. 4. Real Time Navigation Algorithms for LEO Small Satellites using COTS GNSS

    University essay from KTH/Lantmäteri – fastighetsvetenskap och geodesi

    Author : Nathan Groisne; [2023]
    Keywords : PNT; Small Satellite; COTS; GNSS; Navigation; ACS; PNT; små satelliter; COTS; GNSS; navigering; ACS;

    Abstract : 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. READ MORE

  6. 5. The chemical evolution of the Milky Way: pushing APOGEE to higher precision and accuracy

    University essay from Lunds universitet/Astrofysik; Lunds universitet/Fysiska institutionen

    Author : Erik Fridén; [2023]
    Keywords : Physics and Astronomy;

    Abstract : In the recent decade, a rapid increase in all-sky spectroscopic surveys has occurred, and with it, the wealth of observational data and information on our Galaxy. Consequently, numerous detections of new structures, such as new open clusters, accreted and in-situ components, are discovered. READ MORE
