  1. 1. Geodetic analysis for the Very Long Baseline Interferometry Global Observing System

    Författare :Niko Petteri Kareinen; Chalmers University of Technology; []
    Nyckelord :VLBI; GGOS; VGOS; digital back-ends; Earth rotation; DBBC; automated analysis; EOP; UT1;

    Sammanfattning : Very Long Baseline Interferometry (VLBI) is an essential technique forspace-geodesy. It realizes the International Celestial Reference Frame(ICRF) and provides a link between the Earth- and space-fixed coordinatesystems by directly observing all Earth Orientation Parameters (EOP)simultaneously.

  2. 2. Observation strategies for current and future geodetic very long baseline interferometry

    Författare :Niko Petteri Kareinen; Chalmers University of Technology; []
    Nyckelord :NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; ENGINEERING AND TECHNOLOGY; VLBI; automated analysis; Intensives; Earth rotation; VGOS; GGOS;

    Sammanfattning : Geodetic Very Long Baseline Interferometry (VLBI) is an essential technique for space geodesy. It is uniquely capable of simultaneously observing all Earth Orientation Parameters (EOP) and directly giving access to the Earth’s rotation angle (related to Universal Time, UT1). LÄS MER

  3. 3. Observations of Artificial Radio Sources within the Framework of Geodetic Very Long Baseline Interferometry

    Författare :Grzegorz Klopotek; Chalmers University of Technology; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; space geodesy; Monte-Carlo simulations; VGOS; geodetic VLBI; c5 ;

    Sammanfattning : Very long baseline interferometry (VLBI) is a mature and fascinating technique with unique and indisputable applications in radio astronomy, planetary sciences, and space geodesy. The latter discipline is a field of science facilitating our understanding of various global-scale phenomena connected to Earth dynamics. LÄS MER
