  2. 1. Undifferenced GPS for Deformation Monitoring

    Author : Johan Vium Andersson; Lars Sjöberg; Jonas Ågren; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; : deformation monitoring; GPS; modified NGS-parameters; undifferenced GPS-observations; Kalman filter; Geoengineering; Geoteknik;

    Abstract : This thesis contains the development of a deformation monitoring software based on undifferenced GPS observations. Software like this can be used in alarm systems placed in areas where the earth is unstable. READ MORE

  4. 2. Escaping 'death by GPS' : foundations for adaptive navigation assistance

    Author : Fateme Teimouri; Kai-Florian Richter; Henrik Björklund; Sabine Timpf; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; wayfinding; navigation systems; navigation complexity; prominent locations; route generalization; spatial cognition; mental models; route learning; direction giving; Human-centered study.;

    Abstract : Navigating through physical environments has evolved over time from using stars and maps to support the wayfinding, to employing Global Positioning Systems and navigation services. Turn-by-turn guidance of navigation services is an effective way to support wayfinding, but it may not align with the way humans naturally navigate. READ MORE

  5. 3. Quality description in GPS precise point positioning

    Author : Masoud Shirazian; Lars Erick Sjöberg; Jan M. Johansson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; GPS; PPP;

    Abstract : GPS processing, like every processing method for geodetic applications, relies upon least-squares estimation. Quality measures must be defined to assure that the estimates are close to reality. READ MORE

  6. 4. GPS : superficial observations for deeper knowledge of the earth

    Author : Sten Bergstrand; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; VLBI; local ties; GPS; rheology; mantle viscosity;

    Abstract : .... READ MORE

  7. 5. Description and Analysis of Data and Errors in GPS Meteorology

    Author : Borys Stoew; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; atmospheric water vapor; global positioning system; propagation delay; meteorology; ensemble assimilation; GPS;

    Abstract : This report presents the relation between remote sensing techniques used for estimation of atmospheric water vapor content, and numerical weather prediction. The thesis makes an overview of the methods for estimation of the zenith wet/total delay (ZWD/ZTD) for radio waves in the neutral atmosphere, and a statistical description of data in relation to the sampling problem for atmospheric water vapor.
