  1. 1. Design of a 2-D Lattice Flower Constellation for Earth observation applying the twin satellite concept

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

    Author : Julia Martín-Fuertes Brañas; [2023]
    Keywords : 2D Lattice Flower Constellation design; number of satellites; number of planes; revisit time; coverage; optimized constellation; target list; twin satellite concept; FreeFlyer; 2D Lattice Flower Constellation design; antal satelliter; antal plan; återbesökstid; täckning; optimerad konstellation; mållista; tvilling-satellit-koncept; FreeFlyer;

    Abstract : Events such as forest fires or floods are a danger to our Earth’s environment and the people living in it. The sooner they can be detected, the less damage they can cause. An idea arises: use satellites to monitor the Earth and relay information to prevention and rescue organizations in a very short time, regardless of accessibility from ground. READ MORE

  3. 2. 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

  4. 3. 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.

  5. 4. Microsatellite Constellation for Wildfire Monitoring

    University essay from KTH/Geoinformatik

    Author : Citlali Bruce Rosete; [2022]
    Keywords : microsatellite; shortwave infrared sensor; active fire monitoring; burned area detection; satellite constellation; mikrosatellit; kortvågig infraröd sensor; aktiv brandövervakning; detektion av brandhärjat område; satellitkonstellation;

    Abstract : I flera års tid har antalet svåra och okontrollerade skogsbränder ökat i antal. Det finns ett behov av att detektera skogsbränder med hjälp av satelliter som har högre tidsupplösning samt högre geometrisk upplösning än de satelliter som är i bruk idag. READ MORE

  6. 5. On-board processing with AI for more autonomous and capable satellite systems

    University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Author : Tamina Lund; [2022]
    Keywords : Satellite telemetry forecasting; battery degradation prediction; LSTM; artificial intelligence; on-board processing;

    Abstract : While the use of Artificial Intelligence (AI) has faced a sharp up-rise in popularity in ground-based industries, such as for autonomous navigation in the automotive industry and predictive maintenance in manufacturing processes, it is yet only rarely used in space industry. Hence, this thesis aims to investigate the possibilities of using AI for processing on-board Earth-orbiting satellites while in orbit. READ MORE
