  1. 1. Optimisation of line of sight matching to obtain wind vectors from the SIW satellite

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

    Författare :Theresia Hestad; [2021]
    Nyckelord :Remote sensing; Wind measurements; Middle atmosphere; Retrieval; Scan bias; Satellite;

    Sammanfattning : SIW, Stratospheric Inferred Winds, is one of the upcoming Swedish research satellites, aiming to study the winds in the middle atmosphere by measuring the Doppler shifts in molecules such as O3 with a limb viewing sub-mm spectrometer. By conducting simulations on the expected observations, the pointing sensitivity requirement of the satellite was investigated to be able to optimise the matching of the wind vectors. LÄS MER

  3. 2. Design of microcontroller circuit and measurement software for SiC and MOREBAC experiment

    Uppsats för yrkesexamina på avancerad nivå, KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Författare :Mikael André; Hannes Paulsson; [2016]
    Nyckelord :Silicon Carbide; satellite; embedded systems; microcontroller; spaceflight; Kiselkarbid; satellit; inbyggda system; mikrokontroller; rymden;

    Sammanfattning : This paper describes the development of an experiment to test the characteristics and functionality of Silicon Carbide (SiC) components in a space environment. The experiment is a part the "Miniature Student Satellite" (MIST) project, and the "Work on Venus" project, both situated at KTH, Stockholm, Sweden The paper primarily covers the development and implementation of the experiments microcontroller and its software, whilst the construction and development of the test circuit for the transistors is carried out at the same time by another team, and therefore described in a separate paper.

  4. 3. Development and Implementation of Star Tracker Electronics

    Uppsats för yrkesexamina på avancerad nivå, KTH/Rymd- och plasmafysik

    Författare :Marcus Lindh; [2014]
    Nyckelord :miniature star tracker; cubesat; real-time blob detection; FPGA image processing; CMOS image sensor; smartfusion2 SoC; attitude control; hardware development;

    Sammanfattning : Star trackers are essential instruments commonly used on satellites. They provide precise measurement of the orientation of a satellite and are part of the attitude control system. For cubesats star trackers need to be small, consume low power and preferably cheap to manufacture. LÄS MER
