Problems of Construction of the ICRF3 Reference Frame

Transactions of IAA RAS, issue 36, 96–101 (2016)

Keywords: fundamental reference frame, very long baseline interferometry, proper motion of reference radio sources

Abstract

International Celestial Reference Frame (ICRF) is referred to accurate positions of extragalactic radio sources which are observed by the global VLBI network under the operation of the International VLBI Service (IVS). The first version (ICRF1) was announced in 1995, and the second version (ICRF2) in 2009. The floor error of positions of the best radio sources in the northern hemisphere has been improved from 250 to 40 mas. Currently, newly established IAU Working Group has started preparation of the next catalogue, ICRF3. It is expected to be finalized by the General Assembly of IAU in 2018. Apart from traditional activities, the following problems are to be solved:

accurate positions of extragalactic radio sources which are observed
by the global VLBI network under the operation of the International
VLBI Service (IVS). The first version (ICRF1) was announced in 1995,
and the second version (ICRF2) in 2009. The floor error of positions
of the best radio sources in the northern hemisphere has been
improved from 250 to 40 mas. Currently, newly established IAU Working
Group has started preparation of the next catalogue, ICRF3. It is
expected to be finalized by the General Assembly of IAU in 2018.
