  1. 1. Inverse Uncertainty Quantification for Sounding Rocket Dispersion

    Master-uppsats, KTH/Matematik (Avd.)

    Författare :Tove Ågren; [2022]
    Nyckelord :Uncertainty quantification; Bayesian inference; Rocket dispersion; Neural networks; Markov Chain Monte Carlo.; Osäkerhetskvantifiering; Bayesiansk inferens; Raketspridning; Neurala nätverk; Markovkedje-Monte Carlo;

    Sammanfattning : Sounding rocket impact points are subject to dispersion due to uncertainties in simulation model parameters and perturbations of the rocket trajectory during flight. Estimating the area of dispersion assumes that associated model uncertainties and magnitude of perturbations have already been inferred. LÄS MER

  3. 2. Preliminary design of a modular high altitude balloon power distribution system

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

    Författare :Emil Nordqvist; [2020]
    Nyckelord :Power distribution; Power system; High altitude balloon; Battery technology; Electrical Enigineering; Stratospheric Balloon;

    Sammanfattning : This thesis conducts research into different rechargeable battery technologies and their applicability to the high altitude balloon flights conducted at Esrange space center. The research focuses on the possible use of lithium ion batteries’, sodium ion batteries, nickel metal hydrate, and Metal hydridelithiumion batteries. LÄS MER

  4. 3. Wind Forecasts Using Large Eddy Simulations for Stratospheric Balloon Applications

    Master-uppsats, Luleå tekniska universitet/Rymdteknik

    Författare :Ludvig Sjöberg; [2019]
    Nyckelord :Weather Research and Forecasting Model; Large Eddy Simulation; Microscale Meteorology;

    Sammanfattning : The launch of large stratospheric balloons is highly dependant on the meteorological conditions at ground level, including wind speed. The balloon launch base Esrange Space Center in northern Sweden currently uses forecasts delivered through the Swedish Meteorological and Hydrological Institute to predict opportunities for balloon launches.

  5. 4. Investigating new Service System Solutions for High Altitude Balloons : Feasibility Study and Design Challenges

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

    Författare :Joakim Peterson; [2016]
    Nyckelord :High altitude balloon; service system; corona discharge;

    Sammanfattning : The high altitude balloon operations at Esrange Space Center have been goingon since 1972, and about 550 launches have been performed. Their present service system for the high altitude balloons is about 18 years old. To be able to meet the requests from their customers, SSC have started the development of a new service system.

  7. 5. Etablering av kommersiell rymdfart i Sverige : En undersökning om möjligheten att etablera kommersiell rymdfart i samarbete med Sveriges enda rymdbas Esrange Space Center

    Kandidat-uppsats, Södertörns högskola/Turismvetenskap

    Författare :Emma Knutas; Maria Johansson; [2016]
    Nyckelord :Commercial Spaceflight; Esrange Space Center; space science; Kiruna; Kommersiell rymdfart; Esrange Space Center; rymdforskning; Kiruna;

    Sammanfattning : Syftet med vår uppsats är att undersöka Sveriges möjligheter för att etablera kommersiell rymdfart och om detta är en realistisk framtida möjlighet. Vi tittar även på om vissa satsningar borde göras som ett komplement till detta, genom till exempel virtuella upplevelser från jorden. LÄS MER
