IVS VLBI 2010 Workshop on Future Radio Frequencies and Feeds Wettzell / Hoellenstein (Germany), March 18 - 20, 2009 V2C Meeting Wettzell / Hoellenstein (Germany), March 21, 2009

Objectives

The goal of the FRFF Workshop was to develop recommendations to the IVS Directing Board on the definition of the VLBI2010 radio frequencies and the specifications for VLBI2010 feeds. Fixing these parameters is important for future VLBI2010 developments and the realization of VLBI2010 antennas such as the German Twin Telescope Wettzell (TTW). Toward that end, talks and discussions addressed possible options for observation frequency ranges that will allow VLBI2010 systems to achieve the VLBI2010 goal of 1-mm position accuracy in 24 hours, within the real-world constraints imposed by RFI, feed and antenna design, broadband receiver technology, calibration, and other factors.

The FRFF Workshop was mostly geared toward VLBI experts and electronics/RF engineers, who are encouraged to contribute with their expertise to the definition of the VLBI2010 radio frequencies. The workshop was divided into a tutorial part and a part with open contributions.

The presentations and discussions were on the following subjects:

• broadband observation
• feed issues
• polarization
• broadband receiver desing
• radio frequency interference (RFI)
• geodetic ties between VLBI and other techniques (GNSS, SLR, etc.)
• conclusions and recommendations to the IVS Directing Board

You find here the program of the workshop.

Following this 3-day workshop a one-day IVS VLBI2010 Committee (V2C) meeting has been held on March 21^st. You find here the program of the V2C meeting.

Recommendations to the IVS Directing Board

• The initial implementation of the VLBI2010 system needs to be capable of observing the broadband range of 2.2 to ~14 GHz.
• The VLBI2010 system needs to be capable of S/X operation.
• The antenna should allow for a possible future inclusion of Ka-band (32 GHz) operation.
• The complete end-to-end operation of the VLBI2010 system should be demonstrated in a campaign in early 2012. As many antennas as possible should participate.
• A plan should be established for the transition from the legacy S/X system to the VLBI2010 broadband delay system. Such a transition plan can be beneficial for obtaining future funding and will support a timely changeover.
