  3. 3. Space Geodesy Techniques: An Experimental and Theoretical Study of Antenna Related Error Sources

    Author : R. T. Kenneth Jaldehag; Chalmers University of Technology; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; reflector antennas; signal scattering; very long baseline interferometry VLBI ; signal multipath; space geodesy; GPS error sources; geodetic networks; Global Positioning System GPS ; postglacial rebound; choke-ring antennas;

    Abstract : This thesis presents work associated with antenna related error sources, as well as antenna design, in space geodesy utilizing the techniques of Very-Long-Baseline Interferometry (VLBI) and the Global Positioning System (GPS). Geodetic VLBI uses large radio telescopes, often in global networks observing at least a few times per year. READ MORE

  4. 4. Exploring Strategies for the Combination of Multiple Space-geodetic Techniques

    Author : Periklis Diamantidis; Chalmers University of Technology; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Space Geodesy; GNSS; Combination on the Observation Level; EOP; Reference Systems; VLBI; Local Ties;

    Abstract : Space-geodetic techniques are based on signal acquisition from extraterrestrial radio sources that can be used to infer geodetic positioning and define Earth-fixed and inertial reference systems. These techniques, which include Very Long Baseline Interferometry (VLBI) and Global Navigation Satellite Systems (GNSS) among others, exhibit different strengths and weaknesses in recovering parameters of interest.
