Target entity: International VLBI Service for Geodesy and Astrometry
Context triple: [IERS Conventions, usedBy, International VLBI Service for Geodesy and Astrometry]
  • A. International VLBI Service for Geodesy and Astrometry chosen
    The International VLBI Service for Geodesy and Astrometry is an international organization that coordinates Very Long Baseline Interferometry observations to provide precise measurements of Earth’s rotation, reference frames, and celestial positions.
  • B. Very Long Baseline Interferometry
    Very Long Baseline Interferometry is a radio astronomy technique that combines signals from widely separated antennas to achieve extremely high angular resolution and precisely measure geodetic and astronomical parameters.
  • C. European VLBI Network
    The European VLBI Network is an international collaboration of radio telescopes that work together using very long baseline interferometry to achieve extremely high-resolution observations of the radio universe.
  • D. International Celestial Reference System
    The International Celestial Reference System is the standard, high-precision coordinate framework used in astronomy and geodesy to define positions of celestial objects relative to distant quasars.
  • E. space VLBI
    Space VLBI is a radio astronomy technique that extends very long baseline interferometry by placing one or more antennas in space to achieve extremely high angular resolution beyond the limits of Earth-based arrays.
  • F. None of above.
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
