  1. 1. Risk computation for atmospheric re-entry

    University essay from KTH/Rymdteknik

    Author : Florian Teilhard; [2021]
    Keywords : Spacecraft Dynamics; Atmospheric re-entry; Rymdfarkosters dynamik; Atmosfäriska återinträdet;

    Abstract : In the present work, two numerical tools are under scrutiny. Both were made to study the atmospheric re-entry of a spacecraft: DEBRISK computes the trajectory and the survivability of the spacecraft as well as its fragments, and ELECTRA calculates the trajectory of the spacecraft and its fragments, as well as the associated on-ground risk of human casualty.

  3. 2. FORESAIL-2 AOCS Trade Studies and Design

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

    Author : Guillaume Le Bonhomme; [2020]
    Keywords : space engineering; CubeSat; ADCS; AOCS; spacecraft subystems; nanosatellite;

    Abstract : This thesis aims to design a reliable CubeSat platform, including the avionic subsystems that can sustain a high radiation environment for a mission having a lifetime of at least six months. The science instruments put stringent requirements on the platform to achieve and maintain the desired spin rate. READ MORE

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

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

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

    Abstract : 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. READ MORE

  5. 4. The FLARE Suit: A protection against solar radiation in space

    University essay from KTH/Rymdteknik

    Author : Sébastien Ruhlmann; [2019]
    Keywords : ;

    Abstract : FLARE Suit är en enhet som används för att skydda astronauter från intensiv partikelstrålning när de reser ut ur magnetosfären på framtida Deep Space-uppdrag.   Denna dräkt kan skydda mot solpartiklar som på grund av sin höga densitet kan orsaka akut strålningssjuka och leda till överdriven förstöring av inre organ (mag- tarmkanalen, nervsystemet, blodbildande benmärg) och i värsta fall till döden.

  6. 5. In-orbit performance analysis of the image sensors from Pleiades mission

    University essay from Luleå tekniska universitet/Rymdteknik

    Author : Faviola Romero; [2017]
    Keywords : Pleaides mission; Image sensors; CCD; radiation effects on CCDs;

    Abstract : The image sensors embedded in the instruments on board of different satellites are a key aspect in the success of a mission of any type such as Earth observation, astronomy or planetary and universe exploration. The quality of the sensor itself as well as the electronics embedded in the instrument suffer from aging, not only due to the usage, but also due to the space environment factors. READ MORE
