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 sixth GM is the new perspectives of the next generation VLBI system under the theme "VLBI2010: From Vision to Reality". The vision of the VLBI2010 system is gradually being realized. The unprecedented new capabilities of 1-mm positional accuracy and station velocities of 0.1 mm/yr, continuous observational time series for station positions and Earth orientation parameters, and fast turnaround time from observation to geodetic and astrometric result will foster new science and applications.

The content of the meeting will be 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.

Session Title Conveners Description
1 Realization and New Perspectives of VLBI2010 ,
The outstanding VLBI results available today are valuable for various fields of science and research and are needed for many practical applications. Due to its unique features VLBI plays a key role in the maintenance of precise global reference frames, TRF and CRF, and in the provision of all Earth Orientation Parameters. The unprecedented new capabilities of the next generation VLBI system of 1-mm positional accuracy and station velocities of 0.1 mm/yr, continuous observational time series for station positions and Earth orientation parameters, and fast turnaround time from observation to geodetic result will foster new science and applications.
2 Network Stations, Operation Centers, Correlators ,
This session focuses on the recent activities and future plans at VLBI networks, stations and correlators. Presentations about issues that relate to improving VLBI data quality in general and more particularly with regard to "VLBI2010" are solicited. Also welcome are submissions concerning the GGOS Project's contributions to local surveys to determine the spacial vectors from the radio telescopes to co-located geodetic instruments. Network station status reports should be submitted to this session.
3 VLBI Data Structure, Analysis Strategies and Software ,
IVS data are collected at the IVS Data Centers and analyzed by the IVS Analysis Centers. In this session, we call for contributions related to the IVS Data and Analysis Centers' activities and plans for the future. We solicit contributions from the IVS Data Centers concerning data flow, services for users, reliability and timeliness of data exchange between the primary Data Centers. IVS Analysis Centers are invited to contribute papers related to their current activities, development and comparison of models and software used for the data analysis, and assessment of the errors and accuracy of the VLBI results. We expect VLBI data to increase dramatically—by at least a factor of 10, and maybe a factor of 100—in the near future because of VLBI2010. Because of this, we are especially interested in Data Centers and Analysis plans related to automation of data collection, processing and analysis. Presentations related to the comparison and development of analysis strategies are welcome, as our changes that need to be made because of VLBI2010.
4 Interpretation of VLBI Results in Geodesy, Astrometry and Geophysics ,

The analysis of VLBI observations produces time series, long-term average positions and rates, and values of physical parameters. Suggested topics include the use of such VLBI results in modeling geophysical fluids from the atmosphere to the core, nutation/precession, high frequency Earth orientation changes, refinement of the terrestrial and celestial reference frames, interpretation of the motions of specific sites and radio sources, astrophysical investigations, tests of relativity, and other scientific uses of geodetic and astrometric VLBI data. Also included are investigations of the troposphere and the ionosphere by VLBI. Another area is the comparison, validation and combination of VLBI with other space geodetic techniques, and the integration of the techniques within the framework of IAG's Global Geodetic Observing System (GGOS).
5 Progress in Technology Development ,
This session will concentrate on new technology developments in VLBI that have occurred recently or are currently in development. Included (but not limited to) are such topics as 1) development of digital processing technologies in the VLBI signal chain that are expected to soon replace traditional analog BBCs, 2) continuing development and deployment of advanced high-data-rate disk-based recording systems, 3) transmission of raw VLBI data via high speed networks, dubbed e-VLBI, 4) new correlator technologies and techniques, 5) RFI excision techniques, 6) advanced calibration techniques and 7) automation of station operations. Contributors to the session are encouraged to report their progress and ideas on new technologies and methods, and to show how these new developments will improve the overall VLBI program.

Travel Information

Visa. In order to enter Australia you will need a visa, an Electronic Travel Authority (ETA), or an eVisitor—depending on your nationality. Either of these must be obtained before travelling to Australia. The ETA and eVisitor are applied for electronically. eVisitor is available to passport holders from the European Union and a number of other European countries; there is no fee for the online application of eligible passport holders. An ETA can be applied for through a travel agent, airline, specialist service provider or an Australian visa office outside Australia. Eligible passport holders have to pay a fee (currently $20 AUD). If your country is not listed in the ETA or eVisitor eligibility lists, please check with the Australian Embasssy/Consulate in your country on the required visa procedure.

Arriving in Hobart. Most flights to Hobart go via the major hubs of Sydney or Melbourne. At Hobart airport there are no money changing facilities. If you intend to change money to get Australian dollars, you are advised to do that at the Sydney or Melbourne airports. However, there is an ATM at Hobart airport where you can draw money, provided your bank card (and PIN) are set up to work overseas.

Airport transportation. Taxis and airport bus services are available for transport to Hobart and the University of Tasmania. A taxi form the airport is $50-60 AUD and takes about 30-35 minutes. There are two bus services. (1) The Redline Airporter bus meets all incoming flights at Hobart airport. You do not need to book a ticket if you are traveling form the airport to Hobart city (just jump on the bus at the airport), but you do need to book in advance if your are traveling to the airport. The cost is $15 AUD one-way, and $25 AUD return. If you are going to the University Apartments, the bus driver will drop you off at bus stop 14. From bus stop 14 it is still a 10-min walk up a steep hill to the University Apartments. All major hotels are serviced directly. (2) The Southern Airport Pick-up Service will drop you off and collect you at a range of locations in Hobart, including (unlike the Redline Airporter bus) directly at the University's Accommodation Services office. For the Southern Airport mini-bus advance bookings are essential, a 2 or 3 days' notice is advisable. For bookings call +61-(0)3-6231-5080 or e-mail or The cost is $25 AUD one-way from the airport to city locations, including the University.

Tourism. Tasmania is a favorite vacation spot boasting 18 National Parks which protect the largest area of temperate rainforest remaining on earth, a World Heritage Area. The local organizers have assembled a Web page with suggested tours and destinations from short trips to longer journeys. Please visit the GM2010 Tourist Information page to get inspired.

Time. Tasmania observes daylight saving time during the (southern) summer months and is then 11 hours ahead of Univsersal Time: Australian Eastern Daylight Time (AEDT) = UTC + 11 hrs.

Money. Australia's currency is the Australian dollar, made up of 100 cents. There are 5c, 10c, 20c, 50c, $1, and $2 coins, and $5, $10, $20, $50, and $100 notes.
