  1. 1. Investigation of Antenna Radomes in Low Earth Orbits

    University essay from Lunds universitet/Centrum för analys och syntes

    Author : Mathias Manohar Gren; [2023]
    Keywords : Materials; Science; Space; Satellites; Antenna Radomes; Beyond Gravity; Coatings; Physics; Chemistry; Low Earth Orbits; Engineering; Lunds University; Materials Chemistry; Technology and Engineering;

    Abstract : Introduction: This master’s thesis focuses on exploring improved alternative material solutions for antenna radomes used to protect Beyond Gravity Sweden’s satellite antennas in low Earth orbits. Background: As the environment in low Earth orbit is harsh, surface materials on satellites experience high levels of atomic oxygen, ultra violet radiation, thermal-fluctuation, charged particles and micro meteoroids.

  3. 2. Logistical consequences of rapid deliveries in omnichannel retailing : Investigating the impact of 15-minute deliveries on the demand management and order fulfilment process

    University essay from Linköpings universitet/Logistik- och kvalitetsutveckling

    Author : Moa Andersson; Evelina Krassow; [2023]
    Keywords : Logistics; Supply chain management; Supply chain; Supply chain processes; Omnichannel; Omnichannel retailing; Consequences; Order fulfilment; Demand Managment; Process;

    Abstract : The need for fast, flexible, and sustainable deliveries has become a key priority for companies as customers demand more convenience in their purchasing experience. Retailers have responded by developing their logistics into an omnichannel to meet these expectations, which has made the supply chain more complex. READ MORE

  4. 3. Development of GNSS Type Processing for the Characterization of the Mobile Propagation Channel

    University essay from KTH/Fastigheter och byggande

    Author : Adrien Bardou; [2021]
    Keywords : LMS Channel; Multi-paths; GNSS; SCHUN; Simulation; LMS-kanal; flerv¨agar; GNSS; SCHUN; Simulering;

    Abstract : Mobile communication systems are undergoing significant development on increasingly wide frequency bands (5G in particular). To support this development, a detailed characterization of the propagation of electromagnetic waves in L, S and C band between a station (satellite, airborne or ground) and a mobile platform is necessary to analyze and model the phenomena that have a decisive impact on the performance, availability and operability of systems.

  5. 4. Synchronization of Acoustic Sensors in a Wireless Network

    University essay from Linköpings universitet/Datorteknik

    Author : Malin Johansson; [2019]
    Keywords : Synchronization; GNSS; GPS; WSN;

    Abstract : Geographically distributed networks of acoustic sensors can be used to identify and localize the origin of acoustic phenomena. One area of use is localization of snipers by detecting the bullet's shock wave and the muzzle blast. READ MORE

  6. 5. Service Aware Traffic Distribution in Heterogeneous A2G Networks

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

    Author : David Tomic; [2019]
    Keywords : In-flight broadband connectivity; direct air-to-ground communication; satellite air-to-ground communication; forwarding algorithm; forwarding scheme; packet loss; delay; QoS threshold; web cache; web cache hit rate; Bredbandskommunikation i flygning; direkt marknadskommunikation; satellit-till-jord-kommunikation; vidarebefordringsalgoritm; vidarebefordringsschema; paketförlust; fördröjning; QoS-tröskel; webbcache; webcache-träffhastighet;

    Abstract : Airplanes have different ways to connect to the ground, including satellite air-to-ground communication (SA2GC) and direct air-to-ground communication (DA2GC). Each connection/link offers a different varying amount of transmission capacity over flight time. READ MORE
