  1. 1. Undifferenced GPS for Deformation Monitoring

    University dissertation from Stockholm : Infrastruktur

    Author : Johan Vium Andersson; KTH.; [2006]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; : deformation monitoring; GPS; modified NGS-parameters; undifferenced GPS-observations; Kalman filter; TECHNOLOGY Civil engineering and architecture Geoengineering and mining engineering Geoengineering; TEKNIKVETENSKAP Samhällsbyggnadsteknik och arkitektur Geoteknik och gruvteknik 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

  2. 2. Height determination by GPS : A practical experiment in central Sweden

    University dissertation from Royal Institute of Technology, Department of Geodesy and Photogrammetry, Stockholm

    Author : Stig-Göran Mårtensson; Högskolan i Gävle.; KTH.; [2001]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TECHNOLOGY Civil engineering and architecture Surveying; TEKNIKVETENSKAP Samhällsbyggnadsteknik och arkitektur Lantmäteri; Division of Geodesy Reports; geoid; GPS levelling; kriging; height determination;

    Abstract : GPS as a height measuring tool has been widely introduced for solving various tasks within the fields of Geodesy and Engineering Surveying. The obvious advantage of not needing lines of sight when acquiring height differences is, however, darkened by the fact that GPS and traditional spirit levelling have fundamentally different reference systems for heights.

  3. 3. Quality description in GPS precise point positioning

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Masoud Shirazian; KTH.; [2013]
    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

  4. 4. Description and Analysis of Data and Errors in GPS Meteorology

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Borys Stoew; [2004]
    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.

  5. 5. GPS/IMU Integrated System for Land Vehicle Navigation based on MEMS

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Yueming Zhao; KTH.; [2011]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; GPS; IMU; MEMS; integration; Kalman filter; physical constraint; outlier;

    Abstract : The Global Positioning System (GPS) and an Inertial Navigation System (INS)are two basic navigation systems. Due to their complementary characters in manyaspects, a GPS/INS integrated navigation system has been a hot research topic inthe recent decade. Both advantages and disadvantages of each individual systemare analyzed. READ MORE
