Home | IAU Working Group | IERS / IVS Working Group

• Meetings:
• Active: 2006-2009
• WG Chair: Chopo Ma
• Goal: Produce ICRF-2 for IERS / IVS consideration and for submission to the IAU Working Group
• Files: Various files related to ICRF-2 analysis
• Charter:
  • The purpose of the working group is to generate the second realization of the ICRF from VLBI observations of extragalactic radio sources, consistent with the current realization of the ITRF and EOP data products. The working group will apply state-of-the-art astronomical and geophysical models in the analysis of the entire relevant S/X astrometric and geodetic VLBI data set. The working group will carefully consider the selection of defining sources and the mitigation of source position variations to improve the stability of the ICRF. The goal is to present the second ICRF to relevant authoritative bodies, e.g. IERS and IVS, and submit the revised ICRF to the IAU Division I working group on the second realization of the ICRF for adoption at the 2009 IAU general assembly.
