1. 1. LEO Satellite Connectivity for flying vehicles

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Jinxuan Chen; [2023]
   Keywords : LEO satellite network; satellite connectivity strategy; Nash-SAC; flying vehicles; LEO:s satellitnät; Strategi för satellitanslutning; Nash-SAC; flygande fordon;

   Abstract : Compared with the terrestrial network (TN), which can only support limited covered areas, satellite communication (SC) can provide global coverage and high survivability in case of an emergency like an earthquake. Especially low-earth orbit (LEO) satellites, as a promising technology, which is integral to achieving the goal of global seamless coverage and reliable communication, catering to 6G’s communication requirements.

3. 2. Initial Orbit Determination of Resident Space Objects From A Passive Optical Imaging System: : Application to Space Situational Awareness

   University essay from Luleå tekniska universitet/Rymdteknik

   Author : Jessica McKenna; [2023]
   Keywords : Space Situational Awareness; Space Science; Angles-Only Initial Orbit Determination;

   Abstract : 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.

4. 3. Investigation of Antenna Radomes in Low Earth Orbits

   University essay from Lunds universitet/Centrum för analys och syntes

   Author : Mathias Manohar Gren; [2023]
   Keywords : Materials; Science; Space; Satellites; Antenna Radomes; Beyond Gravity; Coatings; Physics; Chemistry; Low Earth Orbits; Engineering; Lunds University; Materials Chemistry; Technology and Engineering;

   Abstract : 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.

5. 4. Ultra Low Frequency Electromagnetic Waves at the Saturn Bow Shock

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Axel Lindberg; Johan Höglund; [2023]
   Keywords : ;

   Abstract : This project aims to research the characteristics and prevalence of ultra low frequency(ULF) waves at the Saturn bow shock with the help of data collected by the space probe CASSINIwhich was in orbit around the planet from 2004 and 2017. ULF waves have been extensively studiedat Earth but not at Saturn, and by studying this phenomenon at Saturn we may gain a deeperunderstanding of it. READ MORE

6. 5. Investigation of a Novel Atmosphere-Breathing Electric Propulsion Platform and Intake

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Kun Feng; [2023]
   Keywords : ABEP; VLEO; DSMC; FMF; Orbital Aerodynamics; ABEP; DSMC; VLEO; FMF; Orbital Aerodynamics;

   Abstract : Very Low Earth Orbit (VLEO) provides many benefits for space missions, including better image resolution for Earth observation, better telecommunication link with ground stations, lower launch cost, lower risk of collisions, and fast end-of-life disposal. The last point in benefit is also the main challenge for placing satellites in VLEO. READ MORE
