  1. 11. Galileo High Accuracy Service SDR Implementation

    University essay from Luleå tekniska universitet/Rymdteknik

    Author : Carles Quilis Alfonso; [2023]
    Keywords : Galileo; GNSS; High Accuracy Service; Software Defined Radio; SDR; Matlab;

    Abstract : GNSS positioning has become a key element in everyday life of millions of people, from the person using google maps to move around an unknown city to the mailman or the DRON pilot who require it to carry out their work. All of them benefit in some way from the GNSS constellations and the position algorithms. READ MORE

  3. 12. Overcoming M&A Challenges : The Function of Knowledge Management, Organisational Members, and Operational Managers in the Context of M&As

    University essay from Linköpings universitet/Institutionen för ekonomisk och industriell utveckling; Linköpings universitet/Filosofiska fakulteten

    Author : Fabian Andersson; Gustav Vilumsons; [2023]
    Keywords : Absorptive Capacity; Knowledge Integration; Knowledge Transfer; Mergers and Acquisitions; Operational Management; Organisational Members;

    Abstract : Problem Mergers and acquisitions are a common way for organisations to extend their operations. By merging two or more organisations into one, the newly formed constellation can access new markets and increase the market presence or control of the supply chain. READ MORE

  4. 13. Design and Analysis of Non-symmetric Satellite Constellations

    University essay from KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

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

    Abstract : 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. READ MORE

  5. 14. Using forest reflectance modelling to estimate albedo for narrow-view satellites

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap; Lunds universitet/Fysiska institutionen

    Author : Nick Bergmans; [2023]
    Keywords : satellite; remote sensing; albedo; surface reflectance; vegetation; forest; machine learning; albedo estimation; Earth and Environmental Sciences;

    Abstract : 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. READ MORE

  6. 15. Constellation Optimization using Genetic Algorithm : Combining SAR & Optical Sensors with AI Requirements

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

    Author : Adrian Pellnäs; [2023]
    Keywords : Satellite Constellation Design; Satellite Constellation Optimization; AI - Artificial Intelligence; Synthetic Apterture Radar; Dual-axis; RegionalCoverage Analysis; Satellitkonstellationsdesign; Optimering av satellitkonstellationer; AI - Artificiell Intelligens; Syntetisk Apertur Radar; Dual-axis; Analys avregional täckning;

    Abstract : With increasing world tensions and improvements of satellites and their sensors, the interest and possibility of using space and satellites for defensive purposes has increased greatly. However, not much research has been conducted into the needs and possibilities of satellite constellations over Sweden, especially using SAR and optical sensors combined with AI object detection.
