1. Deployment Simulations of a Composite Boom for Small Satellites
Sammanfattning : 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. LÄS MER
2. Concurrent Engineering of Small Satellites using Hardware-in-the-loop Simulations
Sammanfattning : The miniaturization of spacecraft has brough the possibility of conducting space missions to a vast portion of private enterprises and scientific institutions. The inaccessibility of modest developers to the resources that governmental agencies and primary contractors utilize to develop conventional satellites has not been an obstacle for them to apply different, more agile and risk-seeking approaches.

3. A database of single scattering properties for hydrometeors at microwave and sub-millimetre frequencies
Sammanfattning : 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. LÄS MER
4. Fundamentals and applications of microplasma sources : Actuating, Sensing, and Nonlinearly Approximating
Sammanfattning : The research presented in this thesis covers a wide range of applications for, and integrations of, a stripline split-ring resonator (SSRR) microplasma source. Common throughout the presented works is the always present, but sometimes secondary, focus on analyzing the light and matter that is emitted as gas is flowed through theplasma of the SSRR. LÄS MER
5. Optics for Earth Observation Instruments
Sammanfattning : 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. LÄS MER
