  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.

    Sammanfattning : This thesis investigates designing and implementing a peer-to-peer (P2P) networking frameworkfor Unity, a popular game engine, intending to offer a scalable and efficient solution forconstructing networked multiplayer games. The research covers an analysis of a P2P networkarchitecture, transport layer protocols, challenges in NAT traversal, and peer list management. LÄS MER

  5. 4. USING N-MODULAR REDUNDANCYWITH KALMAN FILTERS FORUNDERWATER VEHICLE POSITIONESTIMATION

    Master-uppsats, Mälardalens högskola/Akademin för innovation, design och teknik

    Författare :Axel Enquist; [2022]
    Nyckelord :MATLAB; Simulink; Kalman filter; n-Modular Redundancy; Underwater;

    Sammanfattning : Underwater navigation faces many problems with accurately estimating the absolute positionof an underwater vehicle. Neither Global Positioning system (GPS) nor Long Baseline (LBL) orShort Baseline (SBL) are possible to use for a military vehicle acting under stealth, since thesetechniques require the vehicle to be in the vicinity of a nearby ship or to surface and raise its antenna.

  7. 5. Submap Correspondences for Bathymetric SLAM Using Deep Neural Networks

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

    Författare :Jiarui Tan; [2022]
    Nyckelord :Underwater simultaneous localization and mapping; Multibeam echosounder; Point cloud registration; Deep learning; Undervattens simultan lokalisering och kartläggning; Multibeam ekolod; Punktmolnsregistrering; Djupinlärning;

    Sammanfattning : Underwater navigation is a key technology for exploring the oceans and exploiting their resources. For autonomous underwater vehicles (AUVs) to explore the marine environment efficiently and securely, underwater simultaneous localization and mapping (SLAM) systems are often indispensable due to the lack of the global positioning system (GPS).
