The IVS VLBI2010 Project Executive Group (V2PEG) and the International VLBI Service for Geodesy and Astrometry (IVS) are pleased to announce the "IVS VLBI2010 Workshop on Technical Specifications (TecSpec)". It will be hosted by the Bundesamt für Kartographie und Geodäsie (Federal Agency for Cartography and Geodesy) and the Forschungseinrichtung Satellitengeodäsie (Research Institute for Satellite Geodesy) of the Technische Universität München.
The workshop will take place in Bad Kötzting/Wettzell (Germany) on March 1 - 2, 2012. Note that the workshop dates immediately precede the 7th IVS General Meeting, Madrid (Spain) on March 4-7, 2012, in order to facilitate participation at both IVS events.
Download the second circular (issued on Dec. 16, 2011), or the third circular (issued on Feb. 10, 2012).
The IVS and affiliated institutions have developed a vision for future geodetic VLBI observation, correlation and analysis called VLBI2010. Several IVS projects are currently developing next generation antennas and systems to support the new vision. IVS network stations have expressed strong interest in obtaining more complete information on these VLBI2010-related technical developments. In response, the V2PEG is offering this workshop on technical specifications.
The goal of this workshop is to bring scientists and technologists together to provide information and promote discussion about the specifications for VLBI2010 station hardware, all the way from the fast-slewing antennas to wideband feeds and front-ends to back-ends and recorders. Topics also include e-transfer and e-VLBI, monitor and control, and clock distribution. In cases where commercial suppliers for VLBI2010 subsystems exist, contact information will be provided.
The workshop is intended for VLBI station managers, engineers, and others who wish to obtain a better understanding of the VLBI2010 concept from the technical point of view. It will also suggest pathways to enable VLBI2010-compatible upgrades at IVS stations.
The program is composed of invited lectures from VLBI2010 experts, discussion periods, and a tour of the Twin Telescopes Wettzell (TTW). In addition, we encourage everyone to submit poster contributions on any topic related to VLBI2010 technical developments.
Most sessions of the workshops will be devoted to invited talks. The first day of the workshop will concentrate on VLBI2010 System Specifications with the following topics: front ends, calibration and signal distribution, signal processing and recording, e-VLBI and discussion. The second day will address topics about VLBI2010 antenna specification with an overview and several case studies of current VLBI2010-related projects. All sessions will have interactive components to encourage questions and discussion related to the subject material.
An extended poster session on VLBI2010 topics will be held on the afternoon of the first day (Thursday) of the meeting. Poster authors are requested to register contributions with a title and short abstract at the POC (email@example.com) until January 15, 2012. Posters may be displayed during the entire workshop; the size of the poster may not exceed 85 cm (width) x 150 cm (height).
On the second day (Friday) time is reserved for general discussions and for an organized tour to the newly constructed TWIN radio telescope Wettzell (TTW) at the observatory.
