  1. 1. Attitude Dynamics and Control for the Task Scheduling of Agile Earth Observation Satellites

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

    Författare :Renato Franze; [2023]
    Nyckelord :Attitude Dynamics; Attitude Control; Earth Observation; Scheduling; Attityddynamik; Attitydkontroll; Jordobservation; Uppgiftsschemaläggning;

    Sammanfattning : This thesis deals with the scheduling problem for a constellation of Earth observation satellites, focusing on modelling the attitude dynamics to assess the tasking capabilities. A target selection algorithm is developed considering the time dependent manoeuvres between targets and the time-dependent value of the observed targets. LÄS MER

  3. 2. Attitude and orbit control analysis of a solar sail spacecraft for Space sunshade missions in the vicinity of the sub-Lagrange 1 point

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

    Författare :Benjamin Jouanneau; [2022]
    Nyckelord :;

    Sammanfattning : This Master thesis report contains a complete attitude and orbit control analysis for solar sail spacecraft in the Circular-Restricted-3-Body-Reference frame. The overall goal of the project is to drive one solar sail from the edge of the Earth Sphere of Influence to a vicinity of the sub-Lagrange1 point. LÄS MER

  4. 3. Hardware-In-the-Loop Simulation of MIST Attitude Determination and Control System

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

    Författare :Alejandro Vicario; [2022]
    Nyckelord :Functional Testing; HIL; FlightSimulations; ADCS; TestManager; TestStand; Satellite subsystems; Funktionell testning; HIL; flygsimuleringar; ADCS; testledare; TestStand; satellitsub system;

    Sammanfattning : The MIST(MIniature Student saTellite) project is a 3U CubeSat developed by student teams at KTH Royal Institute of Technology in Stockholm. One of the fundamental systems of the satellite is the Attitude Determination and Control System (ADCS), re sponsible for estimating and correcting the satellite’s orientation using magnetic fields and sun sensors.

  5. 4. Attitude control using ion thrusters for solar sailing from Low Earth Orbit to sub-L1

    Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)

    Författare :Celeste Holm; Ida Ygland; [2022]
    Nyckelord :the sunshade project; geoengineering; solar sailing; attitude control; ion thrusters;

    Sammanfattning : The purpose of the study is to evaluate the possibility of using gridded ion thrusters as a means of attitude control for a solar sail as a part of the sunshade project, which aims to place 10^8 solar sail sunshade spacecraft, each with an area of about 10 000 m^2, at the Sun-Earth Lagrangian point L1 in order to reduce Earth's global temperature. Two types of solar sail sunshade spacecraft were studied. LÄS MER

  7. 5. Improving the safe mode robustness of an Earth observation satellite

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