WebThe name ‘GAIA’ was originally derived as an acronym for Global Astrometric Interferometer for Astrophysics. This reflected the optical technique of interferometry that was originally planned for use on the spacecraft. WebSep 29, 2024 · The field of astrometry, through the measurement of the precise positions, distances, and motions of astronomical objects, is a fundamental tool for astrophysics, and has been revolutionised in recent years. The level of accuracy and precision achieved, along with its applicability, determines its potential.

Weboptical plane-of-sky angular astrometry, are also done in the well-known, "absolute" reference frame of the planetary ephemerides, often with frac tional precision that is much finer than can be achieved with other kinds of groundbased observations; they therefore can dramatically refine orbits and ephemerides.
WebFurthermore, radar astrometry can significantly reduce ephemeris uncertainties even for an object whose optical astrometry spans many decades.
