  1. 1. Flight Dynamics Software Industrialisation for Inclined Orbits

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

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

    Sammanfattning : 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. LÄS MER

  3. 2. Conceptual design of an electronic dockingstation and positioner for portable antenna

    Master-uppsats, KTH/Maskinkonstruktion (Inst.)

    Författare :Otto Egeman; Karl Westling; [2022]
    Nyckelord :Antenna; Automatic positioner; Geostationary; Docking station; Antenn; Automatisk inpekning; Geostationär; Dockningsstation;

    Sammanfattning : The presented work in this report is a master’s thesis at the machine design track at KTH Royal Institute of Technology. The work was commissioned by Ovzon through Svea Teknik AB. The T6 antenna in Ovzons antenna terminal portfolio is as of now fully manual in terms of positioning against satellites. LÄS MER

  4. 3. Error Injection Study for a SpaceFibre In-Orbit Demonstrator

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Carlos Abad Garcia; [2020]
    Nyckelord :;

    Sammanfattning : The space electronics sector is shifting towards the New-Space paradigm, in which traditional space-quali_ed and expensive components and payloads are replaced by commercial o_-the-shelf (COTS) alternatives. This change in mentality is accompanied by the development of inexpensive cubesats, lowering the entry barrie in terms of cost, enabling an increase in scienti_c research in space. LÄS MER

  5. 4. Internal charging modelling of the AMBER instrument on-board Jason-3 spacecraft

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Jeremie Hacquart; [2020]
    Nyckelord :Internal Charging; Satellite; Plasma; SPIS; Intern laddning; satellit; plasma; SPIS;

    Sammanfattning : Internal charging is the accumulation of charged particles inside a material. Thisbuild up represents a serious hazard to satellites and instruments exposed to thespace environment. The Van Allen radiation belts constitute one of the worst spaceenvironments for satellites orbiting the earth. LÄS MER

  7. 5. Intradyne Signal Recovery and Equalization for Optical Satellite Links

    Master-uppsats, KTH/Rymd- och plasmafysik

    Författare :Philip Conroy; [2017]
    Nyckelord :;

    Sammanfattning : An optical communication system employing intradyne reception withoffline digital signal processing for a geostationary satellite communicationscenario is presented. The digital signal processing is improvedvia the implementation and comparison of several timing recovery algorithms,and the inclusion of an equalization stage. LÄS MER
