  1. 31. Astrodynamical Missions, Gravitomagnetism and Reference Frames
    Wei-Tou Ni (National Tsing Hua University, Taiwan)
    16/06/2023, 09:00
    Fundamental Physics tests: Gravity, Lorentz violation, general relativity, cosmology etc.
    Oral

    Frame dragging is a crucial aspect of relativistic gravity and a manifestation of gravitomagnetism. After Lense-Thirring papers, over 100 years of theoretical investigation and experimental endeavor have established the precision in the astrodynamical measurement up to 1 % level by Gravity Probe B and LAGEOS-LARES mission. Planned/Proposed astrodynamical missions will measure and separate the...

    Fundamental Physics tests: Gravity, Lorentz violation, general relativity, cosmology etc.
    Oral

    The modern astrogeodetic techniques allow to determine the Earth's rotation around its center of mass with unprecedented accuracy. The orientation of the International Earth reference frame with respect to the geocentric International Celestial Reference Frame is obtained to within 0.1 mas, which corresponds to an equatorial arc of 3 mm. However, the striking harvest of results obtained by...

  3. 23. The LARES and LARES 2 satellites for tests of gravitational physics and frame-dragging
    Ignazio Ciufolini (Agenzia Spaziale Italiana), Antonio Paolozzi (INFN)

    Fundamental Physics tests: Gravity, Lorentz violation, general relativity, cosmology etc.
    Oral

    The two missions of the Italian Space Agency (ASI), LARES and LARES 2 have the main objectives to test the general theory of relativity (GR) and to measure with high accuracy the phenomenon of frame dragging. Frame-dragging is an intriguing phenomenon of GR which implies that a current of mass-energy, such as the rotation of a body, generates spacetime curvature. LARES has already tested...

  4. 41. Verification of the gravitational interaction in the field of the Earth with the LARASE and SaToR-G experiments
    David Lucchesi (Istituto Nazionale di Fisica Nucleare)
    16/06/2023, 11:10
    Fundamental Physics tests: Gravity, Lorentz violation, general relativity, cosmology etc.
    Oral

    The previous experiment LARASE (LAser RAnged Satellite Experiment, 2013-2019) and the current experiment SaToR-G (Satellite Test of Relativistic Gravity, 2020-2024) -- both funded by the National Scientific Committee 2 (CSN2) of the National Institute for Nuclear Physics (INFN) -- have so far allowed to obtain a series of significant results in the study of the gravitational interaction in the...

  5. 72. The role of the GGOS network in the definition of high precision geodynamic parameters
    Cinzia Luceri (e-GEOS S.p.A), Giuseppe Bianco (Agenzia Spaziale Italiana)
    16/06/2023, 11:40
    Fundamental Physics tests: Gravity, Lorentz violation, general relativity, cosmology etc.
    Oral

    The Space Geodesy Centre of the Italian Space Agency is one of the the few core stations of the GGOS (Global Geodetic Oberving System) ground network. A “core station” hosts all the three main space geodetic techniques, namely Satellite Laser Ranging (SLR), Very Long Baseline Interferometry (VLBI) and Global Navigation Satellite Systems (GNSS), precisely co-located in a common area.
    The GGOS...
