  1. 11. Primary Drivers of Sea Level Variability in the North – Baltic Sea Transition Using Machine Learning

    University essay from Göteborgs universitet/Institutionen för geovetenskaper

    Author : David Ek; [2023-01-09]
    Keywords : ;

    Abstract : Global mean sea level is rising, however not uniformly. Regional deviations of sea surface height (SSH) are common due to local drivers, including surface winds, ocean density stratifications, vertical land- & crustal movements and more. READ MORE

  3. 12. Design of a 2-D Lattice Flower Constellation for Earth observation applying the twin satellite concept

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

    Author : Julia Martín-Fuertes Brañas; [2023]
    Keywords : 2D Lattice Flower Constellation design; number of satellites; number of planes; revisit time; coverage; optimized constellation; target list; twin satellite concept; FreeFlyer; 2D Lattice Flower Constellation design; antal satelliter; antal plan; återbesökstid; täckning; optimerad konstellation; mållista; tvilling-satellit-koncept; FreeFlyer;

    Abstract : Events such as forest fires or floods are a danger to our Earth’s environment and the people living in it. The sooner they can be detected, the less damage they can cause. An idea arises: use satellites to monitor the Earth and relay information to prevention and rescue organizations in a very short time, regardless of accessibility from ground. READ MORE

  4. 13. Beam Steering Antenna Based on Continuous Transverse Stub Array and Flat Risley Prism Metasurface Lens

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

    Author : Carl Henriksson; Jonathan Fransson; [2023]
    Keywords : ;

    Abstract : Satellite communication is an integral part of society in this day and era. Due tobandwidth limitations communication frequencies have moved into higher frequencybandwidths. With the advancements in communication comes the demand for more efficientantennas due to the high attenuation of millimeter wavelength frequencies. READ MORE

  5. 14. 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.

  6. 15. Robust Aircraft Positioning using Signals of Opportunity with Direction of Arrival

    University essay from Linköpings universitet/Reglerteknik

    Author : Erik Axelsson; Sebastian Fagerstedt; [2023]
    Keywords : Simultaneous localisation and mapping; direction of arrival; signals of opportunity; extended Kalman filter; positioning;

    Abstract : This thesis considers the problem of using signals of opportunity (SOO) with known direction of arrival (DOA) for aircraft positioning. SOO is a collective name for a wide range of signals not intended for navigation but which can be intercepted by the radar warning system on an aircraft. READ MORE
