  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. Flight dynamics multi-mission software development for optical link planning and execution

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

    Author : Giacomo Dal Toso; [2023]
    Keywords : Generic Planning Tool; Visibility Service; Link Support Service; Visibility Windows; Flight Dynamics; Mission Planning;

    Abstract : The Generic Planning Tool (GPT) is a new software package being developed by the Flight Dynamics team at DLR. In an era where laser communications are becoming more and more relevant to data transmission for space missions, the GPT’s purpose is to compute highly accurate visibility windows and provide a wide variety of support information for both satellite-to-ground and inter-satellite links.

  4. 3. Flight Dynamics Software Industrialisation for Inclined Orbits

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

    Author : Pierrick Houede; [2023]
    Keywords : flight; dynamics; software; FDS; geostationary; orbit; station; keeping; uncontrolled; inclination.;

    Abstract : The geostationary orbit has many applications for Earth observation and telecommunications. Like all satellites, spacecraft in this type of orbit are affected by perturbations. These perturbations can modify the satellites trajectories and, without control, deviate them from their target position. READ MORE

  5. 4. 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

  6. 5. Secure satellite internet usage in high-risk areas
