  1. 1. Deployment Simulations of a Composite Boom for Small Satellites

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Pau Mallol Parera; KTH.; [2013]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; small satellites; deployable structures; high packaging ratio; composites; bi-stable; gravity off-loading system; små satelliter; utfällbara strukturer; kompakt ihoppackning; kompositer; bistabil; tyngdkraftskompenserande system;

    Abstract : The use of small satellites is rapidly growing, especially satellites with masses between 1 and 10 kg and few litres of volume. The main reasons are due to the low development time and cost. Electronics miniaturization and high density integration is enabling the small satellites class to perform more and better tasks and at a lower cost. READ MORE

  2. 2. A database of single scattering properties for hydrometeors at microwave and sub-millimetre frequencies

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Robin Nils Ekelund; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; satellites.; remote sensing; single scattering properties; sub-millimetres; clouds; microwaves; Hydrometeors; water vapour;

    Abstract : Remote sensing observations of hydrometeors (ice or liquid water particles) at microwave and sub-millimetre wavelengths provide important input to numerical weather forecasting through data assimilation and give insight to cloud processes that are relevant for climate prediction. The utilization of such measurements requires information on the single scattering properties (SSP), i. READ MORE

  3. 3. Optics for Earth Observation Instruments

    University dissertation from Gothenburg : Chalmers tekniska högskola

    Author : Arvid Hammar; [2019]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; diamond turning; scientific instruments; THz; spline horns; telescopes; measurements; free-form mirrors; stray light; reflector optics; satellites; tolerancing; off-axis;

    Abstract : The optical system is an essential part of every remote sensing instrument used for detecting electromagnetic waves. Careful design, fabrication and characterization is therefore crucial, especially for satellite-borne missions where the possibility of post-launch repairs is highly limited. READ MORE

  4. 4. Antiparticle identification studies for the PAMELA satellite experiment

    University dissertation from Stockholm : Fysik
