General information

The Institute of Applied Astronomy of the Russian Academy of Sciences (IAA RAS) invites the international VLBI community to attend the 5th IVS General Meeting to be held in St. Petersburg, Russia on March 2-6, 2008.

The IVS holds a technical meeting, called the General Meeting, every two years. The purpose of the meeting is to assemble representatives from all IVS components to share information, hear reports, and plan future activities. The meeting also provides a forum for interaction with other members of the VLBI and Earth science communities.

The keynote of the 5th General Meeting will be the vital contribution of VLBI to the future of global observing systems under the theme of "Measuring the Future". VLBI is a key technique for realizing the global reference frames and studying global change by monitoring the full set of Earth orientation parameters (polar motion, dUT1, celestial pole). Required accuracy levels and long-term stability can only be guaranteed with a rejuvenated VLBI system.

The content of the meeting is of interest to the broad spectrum of IVS members as well as to the wider VLBI and Earth science community. All IVS Associate Members and individuals who have interests in the various applications and research fields of VLBI such as geodesy, astrometry, Earth sciences, and related fields are encouraged to attend the meeting and to make an oral or poster presentation. Non-IVS members are cordially invited to attend the meeting and to make a presentation.

In addition to the General Meeting, several side meetings are organized: an IVS Analysis Workshop, a VLBI2010 Working Meeting, a Working Meeting of the IERS/IVS Working Group on the Second Realization of the ICRF, and an IVS Directing Board meeting. Further, it is planned to visit the VLBI station at Svetloe Observatory, which is located about two hours north of St. Petersburg.
