  1. 6. Design and Analysis of Non-symmetric Satellite Constellations

    Master-uppsats, KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

    Författare :Jomuel Danilo Costales; [2023]
    Nyckelord :Space; Satellite; Constellation; Coverage; Non-symmetric; Walker; Set Cover problem; Greedy algorithm; Space; Satellit; Constellation; Täckning; Icke-symmetrisk; Walker; Set Cover problem; Greedy algoritm;

    Sammanfattning : Satellite constellation design has been a well-studied problem since the beginning of the space age. In recent years new concepts and approaches tried to solve it with fewer satellites whilst guaranteeing coverage to the areas of interest, whether globally or regionally. LÄS MER

  4. 8. Land Use/Land Cover Classification From Satellite Remote Sensing Images Over Urban Areas in Sweden : An Investigative Multiclass, Multimodal and Spectral Transformation, Deep Learning Semantic Image Segmentation Study

    Master-uppsats, Linköpings universitet/Institutionen för datavetenskap

    Författare :Oskar Aidantausta; Patrick Asman; [2023]
    Nyckelord :data fusion; deep learning; land use land cover classification; multiclass; multimodal; remote sensing; semantic segmentation; Sentinel satellite; spectral index; U-Net; Urban Atlas;

    Sammanfattning : Remote Sensing (RS) technology provides valuable information about Earth by enabling an overview of the planet from above, making it a much-needed resource for many applications. Given the abundance of RS data and continued urbanisation, there is a need for efficient approaches to leverage RS data and its unique characteristics for the assessment and management of urban areas.

  5. 9. Methods for Co-Orbital Threat Assessment in Space

    Master-uppsats, KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

    Författare :Mathias Dahlman; [2023]
    Nyckelord :threats in space; threat assessment; Lambert s problem; genetic algorithms; NSGA-II; space surveillance and tracking capabilities; hot i rymden; hotbedömning; Lamberts problem; genetiska algoritmer; NSGA-II; inmätning och övervakning av rymdobjekt;

    Sammanfattning : This study investigates methods for assessing threats in space. Space services are crucial to both civilian and military capabilities, and a loss of such systems could have severe consequences. Space systems are exposed to various types of threats. LÄS MER

  7. 10. Conceptual design of an electronic “on the move” docking station for Ovzon satellite terminal

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Max Attergren; Martin Lindwall; [2023]
    Nyckelord :;

    Sammanfattning : The following report discusses a master's thesis in the field of mechanical design within the Machine Design track at the Royal Institute of Technology. The thesis was commissioned by Svea Teknik AB and Ovzon AB. The project's starting point was an existing product in Ovzon's catalog, a satellite terminal of the T7 model. LÄS MER
