1) The building of the ICRF using VLBI, by Christopher S. Jacobs (Jet Propulsion Laboratory, Caltech/NASA):

1.1) Fundamentals of Radio Interferometry,
1.2) Macro-astrometry and the establishment of the ICRF,
1.3) Micro-astrometry and source structures;

2) Current astrometric standards in the optical and infrared, by Amelia Bayo & Katherine Vieira (UValpo, Chile & CIDA, Venezuela):

2.1) Astrometric Reduction Fundamentals
2.2) Current astrometric reference catalogs: uncertainties and limitations
2.3) Proper motions in astrophysics
2.4) VO tools for astrometry;

3) Gaia as the new optical realization of the ICRS and how it can be tied to the ICRF,  by Francois Mignard (Gaia collaboration & OCA, France):

3.1) Determining positions from scanning satellites: HIPPARCOS and Gaia,
3.2) Defining the Gaia reference system,
3.3) Relating the optical and radio reference systems.

The three main topics of the workshop will have two (2) sessions of 1h 25m each.
