  2. 16. Key Technologies in Low-cost Integrated Vehicle Navigation Systems

    Author : Yueming Zhao; Lars E. Sjöberg; Milan Horemuž; Hossein Nahavandchi; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; GPS; INS; MEMS; error modelling; integration structure; lane detection; camera motion; balance adjustment; sensor array;

    Abstract : Vehicle navigation systems incorporate on-board sensors/signal receivers and provide necessary positioning and guidance information for land, marine, airborne and space vehicles. Among different navigation solutions, the Global Positioning System (GPS) and an Inertial Navigation System (INS) are two basic navigation systems. READ MORE

  4. 17. GNSS hardware biases in code and carrier phase observables

    Author : Martin Håkansson; Milan Horemuz; Anna B. O. Jensen; Lambert Wanninger; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; GNSS; GNSS positioning; hardware biases; phase biases; multi-GNSS; GPS; GLONASS; Galileo; BeiDou; satellite dependency; characterization; android; mass market; Group delay variations; nadir dependence; ionosphere modeling; ionospheric tomography; Geodesy and Geoinformatics; Geodesi och geoinformatik; Geodesi; Geodesy;

    Abstract : GNSS hardware biases appear in code and phase observations, and originates both from the receiver and satellite hardware. The presence of biases in GNSS observations might affect the accuracy in precise GNSS positioning applications, and might also be of relevance in other GNSS applications. READ MORE

  5. 18. Hardware biases and their impact on GNSS positioning

    Author : Martin Håkansson; Anna B. O. Jensen; Milan Horemuz; Jan Johansson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; GNSS positioning; Hardware biases; multi-GNSS; GPS; GLONASS; Galileo; BeiDou; Geodesy and Geoinformatics; Geodesi och geoinformatik;

    Abstract : GNSS hardware biases appear in code and phase observations, and originates both from the receiver and satellite hardware. These biases influence the accuracy in precise GNSS positioning if not handled properly. READ MORE

  6. 19. Tectonic History and Present-Day Deformation in the Zagros Fold-Thrust Belt

    Author : Khaled Hessami; James Jackson; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Earth sciences; Zagros; Orogeny; Unconformities; Iran; Growth folds; Middel East; Tectonics; Models; GPS; basement; Seismicity; Geovetenskap; Earth sciences; Geovetenskap; mineralogi; petrologi och tektonik; Mineral Chemistry; Petrology and Tectonics;

    Abstract : This thesis uses various approaches such as observation of satellite images, field investigations, analogue modeling and GPS measurements to constrain deformation of the basement and sedimentary cover of the Zagros fold-thrust belt in time and space.Focal mechanism solutions of most earthquakes indicate that deformation in the Zagros basement is due to shortening and thickening through numerous thrust faults.

  7. 20. Analysis of Temporal and Spatial Variations in Atmospheric Water Vapor Using Microwave Radiometry

    Author : Per O. J. Jarlemark; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; time series analysis; microwave radiometry; atmospheric turbulence; global positioning system; space geodesy; GPS; meteorology; very long baseline interferometry; VLBI; climatology; radio wave propagation; atmospheric water vapor;

    Abstract : The amount of atmospheric water vapor is highly variable in both time and space. In this thesis some aspects of the variations in the atmospheric water vapor are treated. READ MORE
