  1. 1. Unmanned Aerial Vehicle Positioning Using a Phased Array Radio and GNSS Independent Sensors

    University essay from Linköpings universitet/Reglerteknik

    Author : Carl Rapp; [2019]
    Keywords : Sensorfusion; Kalman filter; Phased Array Radio; UAV; Positioning;

    Abstract : This thesis studies the possibility to replace the global navigation satellite system (GNSS) with a phased array radio system (PARS) for positioning and navigation of an unmanned aerial vehicle (UAV). With the increase of UAVs in both civilian and military applications, the need for a robust and accurate navigation solution has increased. READ MORE

  2. 2. Autonomous Compaction Roller : Temporarily convert a non autonomous compaction machine to become autonomous during endurance testing

    University essay from Blekinge Tekniska Högskola/Institutionen för maskinteknik; Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Author : Sebastian Tuma Fischer; Jojje Sundblad; [2018]
    Keywords : Autonomous system; Compaction machine; Endurance testing; Risk assessment; Self-driving; Autonomt system; Kompakteringsmaskin; Långtidsprov; Riskanalys; Självkörande;

    Abstract : How can a non-autonomous compaction roller be converted to become temporarily autonomous while it performs a 500hours endurance test? Particularlysince the compaction rollers in question is not built to be autonomous and shall not be autonomous after the endurance test is completed. The autonomous system shall also be adaptable to all compaction rollers which Dynapac is developing and shall be moved to another machine when the endurance test is completed. READ MORE

  3. 3. Platforms for Real-time Moving Object Location Stream Processing

    University essay from KTH/Geoinformatik

    Author : Shérazade Gadhoumi; [2017]
    Keywords : Data Stream Management Systems; Data mining; Moving point patterns;

    Abstract : Boarder security is usually based on observing and analyzing the movement of MovingPoint Objects (MPOs): vehicle, boats, pedestrian or aircraft for example. This movementanalysis can directly be made by an operator observing the MPOs in real-time, but theprocess is time-consuming and approximate. READ MORE

  4. 4. GPS Based Flight Motion Capture

    University essay from Chalmers tekniska högskola/Institutionen för rymd- och geovetenskap

    Author : Jonathan Arvidsson; [2016]
    Keywords : KPPP; PPP; RTKLIB; SAR; GPS; GNSS; Motion; Capture;

    Abstract : The objective of this study is to analyse Global Navigation Satellite System (GNSS)processing performance, to determine if it is possible, to capture the shape of a flightpath of an airborne Synthetic Aperture Radar (SAR) radar, with a precision of lessthan 5 cm during the time it takes to record a SAR image, a SAR-run, withoutrelying on a local reference receiver. The precision of position is achieved withthe GNSS processing method Precise Point Positioning (PPP) which uses satelliteinformation corrections and an extended Kalman filter. READ MORE

  5. 5. Evaluate and develop high-performance GPS navigation using free GPS software

    University essay from Chalmers tekniska högskola/Institutionen för rymd- och geovetenskap

    Author : Ronny Videkull; [2015]
    Keywords : GNSS; RTK; SAR;

    Abstract : Synthetic Aperture Radar (SAR) mounted on an aircraft allows us to create images of landscapes. In order to obtain such high resolution images it is crucial to accurately determine the flight-path of the instrument's platform. READ MORE
