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

    Author : Niko Petteri Kareinen; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; VLBI; GGOS; VGOS; digital back-ends; Earth rotation; DBBC; automated analysis; EOP; UT1;

    Abstract : 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.

  4. 2. Simulation studies of new observing concepts for geodetic Very Long Baseline Interferometry

    Author : Grzegorz Klopotek; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Very Long Baseline Interferometry; space geodesy; Monte Carlo simulations; VGOS; c5 ; Moon; UT1-UTC;

    Abstract : Very Long Baseline Interferometry (VLBI) is a space-geodetic technique in which observations are carried out simultaneously by radio telescopes separated by hundreds or thousands of kilometers. The time difference of signal reception between the telescopes is the basic observable used in geodetic VLBI. READ MORE

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

    Author : Niko Petteri Kareinen; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; VLBI; automated analysis; Intensives; Earth rotation; VGOS; GGOS;

    Abstract : 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). READ MORE
