1. Initial Orbit Determination of Resident Space Objects From A Passive Optical Imaging System: : Application to Space Situational Awareness
University essay from Luleå tekniska universitet/RymdteknikAbstract : The probability of satellite collisions and disintegrations cluttering the near-Earth orbital environmentis ever-growing. This is especially true for the congested Low Earth Orbit (LEO) regime; once a critical density of objects is reached, a collisional cascading is projected to generate runaway growth of theorbital population.

2. Investigation of Antenna Radomes in Low Earth Orbits
University essay from Lunds universitet/Centrum för analys och syntesAbstract : Introduction: This master’s thesis focuses on exploring improved alternative material solutions for antenna radomes used to protect Beyond Gravity Sweden’s satellite antennas in low Earth orbits. Background: As the environment in low Earth orbit is harsh, surface materials on satellites experience high levels of atomic oxygen, ultra violet radiation, thermal-fluctuation, charged particles and micro meteoroids.

3. Simulations of the Tenuous Upper Atmospheres of Exoplanets
University essay from Lunds universitet/Astrofysik; Lunds universitet/Fysiska institutionenAbstract : Over the last decade, the interest in research on extraterrestrial planets has expanded dramatically. With the number of confirmed exoplanets having increased tenfold over the last ten years, we now know that many different types of exoplanets exist. READ MORE

4. Investigating a possible dearth of stars with zero angular momentum in the solar neighbourhood.
University essay from Lunds universitet/Astronomi - Genomgår omorganisation; Lunds universitet/Fysiska institutionenAbstract : Background. Carlberg & Innanen (1987) first proposed the idea of measuring the solar re- flex velocity (the velocity of the Sun around the galactic centre), Vg,⊙, using the momenta of the stars in the solar neighbourhood. The proposal was a consequence of the work of L. READ MORE

5. Radiation Shielding Simulations for Small Satellites on Geostationary Transfer Orbit
University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknikAbstract : The emergence of small and affordable satellites has led to rapid growth in the number of launched satellites over the past two decades. To save costs, small satellites often use mass-produced electronic components not explicitly designed for the radiation environment of space, which reduces reliability and makes them unsuitable for higher orbits.
