  1. 1. Space Rider System: GNC and System Model Improvements

    Master-uppsats, KTH/Rymdteknik

    Författare :Simon Vial; [2022]
    Nyckelord :Space Rider System; Disturbance Modelling; Maneuver Optimization; Space Rider System; Modellering av Störningar; Manöveroptimering;

    Sammanfattning : As part of a continuous trend of the space sector for obtaining higher performance space science and Earth observations, there is an increasing demand for higher requirements in pointing accuracy and disturbance prediction. The Space Rider System (SRS) is a Low Earth Orbit (LEO) reusable vehicle that aims at answering to that demand. LÄS MER

  3. 2. Feasibility of DC microgrids for rural electrification

    Master-uppsats, Högskolan Dalarna/Energiteknik

    Författare :Krishna Prasad Vijayaragavan; [2017]
    Nyckelord :Solar PV; Microgrids; DC; Low Voltage DC; Rural electrification; Pvsyst; Simulink; Power converters; boost converter; MPPT; performance ratio.;

    Sammanfattning : DC system and DC microgrids are gaining popularity in recent times. This thesis suggests a method to state the workability of a DC based PV system using the softwares Simulink, PVsyst and HOMER. The aims of this project include suggesting a DC based architecture, finding out the performance ratio and a cost analysis. LÄS MER

  4. 3. Mission Concept for a Satellite Mission to Test Special Relativity

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

    Nyckelord :BOOST; Special Relativity; Kennedy Thorndike; Eclipse duration; Ground visibility; Downlink feasibility; 3-axis stabilization; Spin stabilized satellite; Solar array estimation; Battery size estimation.;

    Sammanfattning : In 1905 Albert Einstein developed the theory of Special Relativity. This theory describes the relation between space and time and revolutionized the understanding of the universe. While the concept is generally accepted new experimental setups are constantly being developed to challenge the theory, but so far no contradictions have been found. LÄS MER
