  1. 1. Methods for Multisensory Detection of Light Phenomena on the Moon as a Payload Concept for a Nanosatellite Mission

    Master-uppsats, Luleå tekniska universitet/Rymdteknik

    Författare :Andreas Maurer; [2020]
    Nyckelord :Moon; TLP; Transient Lunar Phenomena; Image Processing; GPU; Nanosatellite; CubeSat; Nvidia Jetson Nano; OpenCL; CUDA; Telescope; Payload Concept; C C ; background subtraction; connected component labelling; FPGA;

    Sammanfattning : For 500 years transient light phenomena (TLP) have been observed on the lunar surface by ground-based observers. The actual physical reason for most of these events is today still unknown. LÄS MER

  3. 2. Design, Fabrication and Modelling of Three Axis Floating Satellite Simulator

    Master-uppsats, Luleå tekniska universitet/Rymdteknik

    Författare :Junaidh Shaik Fareedh; [2017]
    Nyckelord :;

    Sammanfattning : The Floating Satellite (FloatSat) system project which has been developed at the ‘Department of Aerospace Information Technology - University of Würzburg’ is used to test, develop and implement various attitude control algorithms and strategies for small satellites [1]. The FloatSat project is designed to operate on a Frictionless air bearing surface that works with compressed air flowing distributed on a hemisphere. LÄS MER

  4. 3. An Orbit Control System for UWE-4 Using the High Fidelity Simulation Tool Orekit

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

    Författare :Pouyan Azari; [2017]
    Nyckelord :Orbital mechanics; astrodynamics; small satellites; orbit control;

    Sammanfattning : Cubesats are picosatellites that have a mass of less than 1.3kg and have a shape of acube. As a result of their low cost of development and launch, cubesats are gainingpopularity in industry and academia. These satellites are also a cost-efective way forspace technology demonstrations.

  5. 4. Increasing Spacecraft Autonomy through Embedded Neural Networks for Semantic Image Analysis

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

    Författare :Andreas Schartel; [2017]
    Nyckelord :Autonomy; Embedded; Neural Networks; Image Analysis; FPGA;

    Sammanfattning : In the scope of this thesis, a possible usage of embedded artificial neural networks for on-board image analysis is investigated. After an introduction which imparts basic knowledge about artificial neural network and autonomy in spaceflight, a possible system design is elaborated based on previously defined reference scenarios.

  7. 5. A Vision Based Sensor System For Spacecraft Relative Navigation

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

    Författare :Sebastian Stauch; [2016]
    Nyckelord :;

    Sammanfattning : Docking is one of the crucial key elements in many aerospace applications and missions where despite all endeavors and precautions accidents and incidents occur far too often. Those events can lead in the worst case scenario to a total loss of the space system and payload. LÄS MER
