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

   Author : Yueming Zhao; Lars Sjöberg; Milan Horemuž; Krzysztof Gajdamowicz; KTH; []
   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

5. 3. Studies of Atmospheric Water Vapor Using the Global Positioning System

   Author : Ragne Emardson; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; troposphere; microwave radiometry; climatology; radiosondes; atmospheric water vapor; Global Positioning System; time series analysis; VLBI; space geodesy; GPS; Very Long Baseline Interferometry; meteorology; radio wave propagation; Kalman filtering;

   Abstract : Atmospheric water vapor is of fundamental interest in the Global Positioning System (GPS) and Very Long Baseline Interferometry (VLBI) techniques. These techniques are based on the timing of radio waves propagating through the atmosphere. READ MORE

6. 4. 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.

7. 5. Precise kinematic GPS positioning with Kalman filtering and smoothing

   Author : Patric Jansson; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES;

   Abstract : The Global Positioning System (GPS) has proven to be auseful tool for the determination of positions of a widevariety of moving platforms to accuracies in the order of a fewcentimetres. One of the critical aspects of precise kinematicGPS positioning at the centimetre level is the determination ofinteger carrier phase cycle ambiguities. READ MORE
