  1. 1. Quadcopter Control System Design and Implementation with LQR assisted by Kalman Filter: An Experimental Study

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Ludwig Horvath; Martin Petré; [2023]
    Keywords : ;

    Abstract : This study stems from the audacious assumption that two bachelor students could successfully construct a functional quadcopter from scratch, covering both software and hardware aspects. The project begins by establishing a foundation for modeling the quadcopter dynamics, including derivation and linearization techniques for implementing a linear quadratic regulator (LQR). READ MORE

  3. 2. Radio based Cooperative Positioning for Vehicle-to-Vehicle Systems in Urban Scenarios

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Hao Wu; [2018]
    Keywords : V2V; V2X; CKF; SUMO; GemV2; ns3; algorithm; positioning; urban positioning; non-GPS; Technology and Engineering;

    Abstract : This master thesis aims at improving vehicle positioning in high-speed movement scenarios where global navigation satellite system (GNSS) does not work well. The standard 802. READ MORE

  4. 3. Enhancements in LTE OTDOA Positioning for Multipath Environments

    University essay from Linköpings universitet/Kommunikationssystem

    Author : Ivar Olofsson; [2016]
    Keywords : positioning; TDOA; NLOS bias; multiple TOA candidates; probabilistic method; ML estimation; LTE; simulation;

    Abstract : By using existing radio network infrastructure, a user can be positioned even where GPS and other positioning technologies lack coverage. The LTE Positioning Protocol (LPP) supports user Reference Signal Time Difference (RSTD) reports based on the Time of Arrival (TOA) for a Positioning Reference Signal (PRS). READ MORE

  5. 4. Navigation and Autonomous Control of a Hexacopter in Indoor Environments

    University essay from Lunds universitet/Institutionen för reglerteknik

    Author : Johan Fogelberg; [2013]
    Keywords : Technology and Engineering;

    Abstract : This thesis presents methods for estimation and autonomous control of a hexacopter which is an unmanned aerial vehicle with six rotors. The hexacopter used is a ArduCopter 3DR Hexa B and the work follows a model-based approach using Matlab Simulink, running the model on a PandaBoard ES after automatic code generation. READ MORE

  6. 5. Design and implementation of temporal filtering and other data fusion algorithms to enhance the accuracy of a real time radio location tracking system

    University essay from Avdelningen för elektronik, matematik och naturvetenskap

    Author : Zohaib Mansoor Malik; [2012]
    Keywords : Kalman filter; Inertial sensor; Location tracking; Temporal filtering;

    Abstract : A general automotive navigation system is a satellite navigation system designed for use in automobiles. It typically uses GPS to acquire position data to locate the user on a road in the unit's map database. READ MORE
