  1. 1. Risk Assessment for Space Debris Collisions

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

    Författare :Kenny Andersson; [2023]
    Nyckelord :space debris; NASA standard breakup model; satellite fragmentations; satellite fragmentation modelling; space surveillance and tracking; ESA MASTER; collision risk; risk assessment; space situational awareness; rymdskrot; NASA standard breakup model; satellitfragmentering; modellering av satellitfragmentering; inmätning och övervakning av rymdobjekt; ESA MASTER; kollisionsrisk; riskbedömning; rymdlägesbild;

    Sammanfattning : The increasing reliance on space infrastructure and its rapid expansion necessitate the development and enhancement of tools for space debris and fragmentation research. Accurate prediction of the risks associated with satellite fragmentation requires comprehensive understanding of the dynamics involved. LÄS MER

  3. 2. Compact Digital Track Maps: Enhancing Train Traveller Information at the Crossing of Accuracy and Availability : A comparative analysis of algorithms for generating compact representations of railway tracks

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

    Författare :Adam Andersson; [2023]
    Nyckelord :Train positioning; Digital track map; Digital map generation; Position measurement; Global navigation satellite system; Cartography; Tågpositionering; Digitala spårkartor; Generering av digitala kartor; Positionsmätning; Satellitnavigation; Kartograf;

    Sammanfattning : Trains are constrained to the railway tracks they operate on. This can be leveraged for absolute train positioning, where a train’s position can be mapped onto a digital track map (DTM). Extensive research has been dedicated to enhancing the accuracy of DTMs. LÄS MER

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

    Master-uppsats, Linköpings universitet/Logistik- och kvalitetsutveckling

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

    Sammanfattning : 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. LÄS MER

  5. 4. Indoor 5G Positioning using Multipath Measurements

    Master-uppsats, Linköpings universitet/Institutionen för systemteknik

    Författare :Andreas Lidström; Martin Andersson; [2022]
    Nyckelord :Multipath Propagation; 5G Networks; Target Tracking; Sensor Fusion; Positioning; Particle Filter; Kalman Filter;

    Sammanfattning : Positioning with high precision and reliability is considered as an important feature of new wireless radio networks such as 5G. In areas where satellite positioning is not available or is not reliable enough, 5G can work as an alternative. An example is inside factories where autonomous vehicles might need to be positioned in complex environments. LÄS MER

  7. 5. Autonomous Landing of an Unmanned Aerial Vehicle on an Unmanned Ground Vehicle in a GNSS-denied scenario

    Master-uppsats, Linköpings universitet/Reglerteknik

    Författare :Alexander Källström; Albin Andersson Jagesten; [2020]
    Nyckelord :Unmanned Aerial Vehicle; Unmanned Ground Vehicle; Autonomous Landing; Ultra-Wide Band; Proportional Navigation; GNSS-denied Scenario; Gazebo;

    Sammanfattning : An autonomous system consisting of an unmanned aerial vehicle (UAV) in cooperation with an unmanned ground vehicle (UGV) is of interest in applications for military reconnaissance, surveillance and target acquisition (RSTA). The basic idea of such a system is to take advantage of the vehicles strengths and counteract their weaknesses. LÄS MER
