  1. 1. Fiberoptiska sjökablar - Skyddad allmännytta eller potentiellt maktinstrument vid konflikt?

    Kandidat-uppsats, Lunds universitet/Statsvetenskapliga institutionen

    Författare :Peter Lindén; [2023]
    Nyckelord :Digital infrastruktur; sjökablar; internationella relationer; neoliberalism; neorealism; Law and Political Science;

    Sammanfattning : One of today’s most valuable trade routes consists of digital submarine cables trafficking the seabed of the oceans. Our modern society depends on fast and secure digital connections for economic transactions, government for vital functions and military communication. LÄS MER

    Sammanfattning : I den här rapporten behandlas ett Systems Engineering arbete där en undersökning har utförts på möjligheten att docka en autonom undervattensfarkost med den nya generationens ubåt A26. I arbetet har fokus legat på de tidiga stegen inom Systems Engeineering disciplinen. LÄS MER

  5. 4. Design and Evaluation of V/UHF Satellite Communication Antennas for Naval Applications

    Master-uppsats, KTH/Elektroteknisk teori och konstruktion

    Författare :Hampus Bäckström; [2018]
    Nyckelord :Antenna design; Antenna simulations; QHA; Submarine communication; SatCom; MUOS; Legacy; Antenndesign; Antennsimulering; QHA; Ubatskommunikation; Satellitkommunikation; MUOS; Legacy;

    Sammanfattning : In this master thesis, compact antenna design aimed towards naval applicationshave been designed, analyzed and evaluated. There is a recentinterest in the development of compact antennas to be used for smallersubmarine models, and with a smaller hull on a submarine, communicationand antenna systems must be adapted and minimized, which limitsantenna design.

  7. 5. Software defined acoustic underwater modem

    Master-uppsats, Akademin för innovation, design och teknik; Akademin för innovation, design och teknik

    Författare :Jakob Lindgren; [2011]
    Nyckelord :underwater; modem; signal processing;

    Sammanfattning :   Today many types of communication are employed on seagoing vessels, such as radio, satellite and Wi-Fi but only one type of communication is practical for submerged vessels, the acoustic underwater modem. The "off-the-shelf" modems are sometimes difficult to update and replace, especially on a large submarine. LÄS MER
