1. 1. Design and Implementation of a Rocket Launcher Hybrid Navigation

   Master-uppsats, KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

   Författare :Omar Ugolini; [2023]
   Nyckelord :launch vehicle navigation; delayed Kalman filter; strapdown; navigering av bärraketer; fördröjt Kalman-filter; strapdown;

   Sammanfattning : Rocket Factory Augsburg (RFA) a German New Space Startup is developing a three-stage rocket launcher aiming at LEO/SSO orbits. A fundamental responsibility of the GNC team is the development of the rocket navigation algorithm to estimate the attitude, position, and velocity allowing the guidance and control loops to autonomously steer the rocket.

3. 2. Towards Navigational Aids using Augmented Reality for People with Alzheimer’s Disease in Outdoor Environments : A user study using HoloLens 2 around a University campus

   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Léa Prémont; [2023]
   Nyckelord :Augmented reality; Alzheimer’s disease; Navigation; Assistive technology; HoloLens 2; Optical See-Through; Localization; Kalman filter; Hologram; TLX; SUS; Réalité augmentée; Alzheimer; Navigation; Technologie d’assistance; HoloLens 2; Optical See-Through; Localisation; Filtre de Kalman; Hologramme; TLX; SUS; Förstärkt verklighet; Alzheimers sjukdom; Navigering; Tekniska hjälpmedel; HoloLens 2; Optisk genomskinlighet; Lokalisering; Kalman-filter; Hologram; TLX; SUS;

   Sammanfattning : This paper investigates the potential of augmented reality (AR) as a navigational aid for individuals with Alzheimer’s disease (AD), offering innovative solutions to the evolving challenges of AD care. As the disease progresses, patients often require more assistance and may transition to care centers, resulting in reduced independence. LÄS MER

4. 3. RoBuoy : Dynamic Positioning of an Autonomous Buoy using GNSS

   Kandidat-uppsats, KTH/Mekatronik

   Författare :Erik Anderberg; Martin Olanders; [2021]
   Nyckelord :Autonomous; Buoy; GPS; GNSS; Robot; Mechatronics; Dynamic positioning; Autonom; Boj; GPS; GNSS; Robot; Mekatronik; Dynamisk positionering;

   Sammanfattning : Buoys anchored to the seabed are often used for marking courses in competitive sailing and other water sports, but they may need to be relocated several times per day. To avoid the time and fuel consuming labour of raising and moving the anchors, a prototype of an autonomous buoy using electric motors to maintain its position was built and tested. LÄS MER

5. 4. A Comparison of Smartphone GPSL1 and Galileo E1-B/C Spoofing Resilience

   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Torbjörn Leksell; [2021]
   Nyckelord :GNSS; Spoofing; GPS; Galileo; Smartphone; GPU; Signal Simulation; GNSS; Förfalskning; GPS; Galileo; Smarttelefon; GPU; Signalsimulator;

   Sammanfattning : Location-based services have grown in importance as smartphones, and location-based applications have become an integral part of everyday life. While Global Navigation Satellite Systems (GNSSs) provide the most accurate position determination, open service GNSS signals remain unprotected and susceptible to spoofing attacks. LÄS MER

7. 5. Utvärdering av Galileo GNSS med statisk mätning

   Kandidat-uppsats, Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

   Författare :Daniel Carlsson; Johan Johansson; [2020]
   Nyckelord :Galileo; GNSS; Static surveying; Galileo; GNSS; Statisk mätning;

   Sammanfattning : Galileo är ett Global Navigation Satellite System (GNSS) som används för positionering. Förutom Galileo finns även Global Positioning System (GPS) och Globalnaya Navigatsionnaya Sputnikovaya Sistema (GLONASS) vilka är de idag enda fullt operativa systemen. LÄS MER
