VLBI: A fascinating technique for geodesy and astrometry VLBI provides an important linkage to astronomy through, for instance, the determination of very precise coordinates of extragalactic radio sources Additionally, it contributes to determining parameters of relativistic and cosmological models
Very Long Baseline Interferometry - an overview - ScienceDirect Very Long Baseline Interferometry (VLBI) is defined as a technique that measures the position of radio antennas relative to radio sources in quasars, achieving submillimeter precision in relative position vectors It supports earthquake studies by providing important geometric information for the definition of geodetic reference systems like the International Terrestrial Reference Frame (ITRF
VLBI: A fascinating technique for geodesy and astrometry The Very Long Baseline Interferometry (VLBI) technique has been employed for more than 30 years in geodesy, geophysics, and astronomy, and results of geodetic VLBI have been presented and interpreted in a multitude of publications by hundreds of authors
Space very long baseline interferometry in China - ScienceDirect Space very long baseline interferometry (VLBI) has unique applications in high-resolution imaging of the fine structure of astronomical objects and high-precision astrometry due to the key long space–Earth or space–space baselines beyond the Earth’s diameter China has been actively involved in the development of space VLBI in recent years
