  1. 1. Real-Time Navigation for Swarms of Synthetic Aperture Radar (SAR) Satellites

    University essay from Luleå tekniska universitet/Rymdteknik

    Author : Antoni Eritja Olivella; [2024]
    Keywords : SAR; Real-time orbit determination; Real-time baseline determination; swarms; satellite; formation flying;

    Abstract : The pursuit of precision and flexibility in satellite missions has led to an increased number of formation flying missions being developed. These systems consist of multiple satellites flying at close distances (from a few kilometres to a few meters) to achieve common objectives. READ MORE

  3. 2. Turning the tide on marine biodiversity loss: How Swedish coastal cities are leveraging citizen interaction to improve conservation outcomes

    University essay from Lunds universitet/Internationella miljöinstitutet

    Author : Martine Deinum; [2023]
    Keywords : Marine spatial planning; urban planning; blue space; program theory; citizen interaction; coastal conservation; Earth and Environmental Sciences;

    Abstract : Rapid coastal urbanization and declining marine biodiversity rates are complex problems that require broad, integrated sets of solutions. Although isolating nature from human impact prevails as the standard conservation approach, social-ecological systems require more holistic solutions. READ MORE

  4. 3. Collaborative Mapping with Drone Swarms Utilizing Relative Distance Measurements

    University essay from Linköpings universitet/Reglerteknik

    Author : Johan Forsman; Carl Tidén; [2023]
    Keywords : ;

    Abstract : The field of use for unmanned aerial vehicles, UAVs, has completely exploded in the last decade. Today they are used for surveillance missions and inspecting places that are difficult for people to access. To increase the efficiency and robustness in the execution of these types of missions, swarms of cooperating drones can be used. READ MORE

  5. 4. Sensorless Hybrid Field-Oriented Control Two-Phase Stepper Motor Driver

    University essay from Linköpings universitet/Reglerteknik

    Author : Emil Lydell; [2023]
    Keywords : Stepper motor; Field-Oriented Control; FOC; Driver; Two-Phase; 2-Phase;

    Abstract : Hybrid stepper motors are small electrical motors with high torque production, compared with other electrical motors of the same size. Hybrid stepper motors are reliable in open-loop systems, in Sinusoidal mode, but with a drawback of high power consumption. READ MORE

  6. 5. Radio Environment Compensation in a Narrowband IoT Positioning System : Using Radio Signal Metrics Between Stationary Devices

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

    Author : Elin Berglund; [2023]
    Keywords : Positioning; IoT; machine learning; range estimation; Positionering; IoT; maskininlärning; avståndsuppskattning;

    Abstract : The Internet of Things (IoT) has emerged as a powerful tool for meeting our need to collect information about and interact with our environments. One important aspect of this technology is positioning which imposes requirements on both the energy consumption and the arrangement of the systems. READ MORE
