  1. 6. Analysis of Passive Attitude Stabilisation and Deorbiting of Satellites in Low Earth Orbit

    Master-uppsats, Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Författare :Benjamin Hawe; [2016]
    Nyckelord :electrodynamic; electrodynamic tether; EDT; drag augmentation; drag sail; drag balloon; passive attitude stabilisation; passive; attitude; stability; low earth orbit; LEO; deorbit; de-orbit; Post Mission Disposal; TeSeR;

    Sammanfattning : Orbital debris poses a serious threat to ongoing operations in space.  Recognising this threat, the European Commission has funded the three-year Technology for Self Removal (TeSeR) project with the goal of developing a standard scalable Post Mission Disposal (PMD) module to remove satellites from orbit following the completion of their mission.

  3. 7. Innovative Gyroless Attitude Estimation Method

    Master-uppsats, KTH/Mekanik

    Författare :Paul Dermarkar; [2013]
    Nyckelord :;

    Sammanfattning : A key aspect in Attitude and Orbital Control Systems (AOCS) is the ability to estimateaccurately a spacecraft’s attitude and angular rate. While a classic gyrometer and star-trackerhybridization features high performances, gyroless solutions using only star-trackers as attitudesensors are often chosen to reduce the mission’s cost, when possible.

  4. 8. Modelling and Simulation ofGNC/AOCS Systemsfor Conceptual Studies

    Master-uppsats, KTH/Mekanik

    Författare :Louise Lindblad; [2013]
    Nyckelord :;

    Sammanfattning : The preliminary design of Guidance, Navigation, and Control (GNC) algorithms andAttitude and Orbital Control Systems (AOCS) for spacecraft plays an important rolein the planning of a space mission. Many missions require accurate positioning andattitude control to be able to full the mission objectives. LÄS MER
