  7. 5. Simulation studies of new observing concepts for geodetic Very Long Baseline Interferometry

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

    Sammanfattning : 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. LÄS MER
