RadioNet3 Workshop: Multi-Frequency mm-wave Radio Telescopes & Other Software Controlled Operations

We are pleased to announce the 4th RadioNet3 European Radio Astronomy Technical Forum Workshop. This event will take place from Monday, October 5, 09:00, until Wednesday October 7, 2015, 17:00, at the INAF - Arcetri Astrophysical Observatory, in Florence, Italy. There will be a workshop dinner on Tuesday 20:00h. This meeting is a continuation of a series of technical workshops combining several aspects of engineering and operational issues at European radio observatories. It provides the unique opportunity to cross border the different communities and to learn what ‘the others' are doing and enhance communication between engineers, scientists and operators.
The Workshop is sponsored and organized by the EU Consortium RadioNet3 within the Seventh Framework Programme of the European Commission. Engineers, scientists, and operators working at, and observing with, our radio telescopes are welcome to present their interesting work in an oral or poster presentation. For information on past meetings in this series see


The workshop will provide an opportunity for joint discussions between scientists and engineers about the benefits of enabling simultaneous or near-simultaneous high frequency VLBI observations with radio telescopes. This capability results in:
a) more effective use of observing time for monitoring projects which benefit from observations at multiple frequencies;
b) a direct improvement in the sensitivity of observations at high frequencies, through a significant increase in the coherence time, and
c) the enabling of high precision "bona fide" astrometry, in the frequency domain, at mm wavelengths.

This workshop will also provide a platform for new and approved procedures for software controlled operations of radio telescopes. Operating single dish as well as interferometer based radio astronomy observatories requires sophisticated computer control of the entire telescope system. The software hereto was historically written at the various institutes leading to a huge variety of hardware control, operation and data analysis software.

Some TOPICS to address are the following:

1) For the Implementation of (near) Simultaneous observations at mm-wave bands:

  • mm-VLBI Studies and Key Science Case(s):
    • Astronomical Studies using continuum and spectral line observations
    • Analysis Methods and Results from current instruments using multifrequency observations
  • Defining science driven requirements
    • Achievable sensitivity and mapping fidelity
    • Simulation studies of the performance of a multi-frequency mm-VLBI network of European telescopes
  • Exploring the engineering possibilities:
    • Existing technical solutions for simultaneous multi-frequency observations;
    • Possibilities of technical solutions for other sites.
  • Plan for a realisation of a European network.

2) For the Software Control of Radio Telescopes section:

  • Effective utilisation of radio telescopes:
    • Dynamic scheduling
    • Remote observing
    • Automated observing
  • Observing modes:

Registration for the Symposium should be done through the ERATec website before SEPTEMBER 1, 2015.

Please have a look on our workshop site for updated information:

The meeting will be informal and should offer lots of time for discussions. Each presentation is limited to a maximum of about 20 minutes with an additional 10 minutes for discussion.
Deadline for abstract submission is SEPTEMBER 1, 2015.

By this date we need the title of your talk or poster presentation and a comprehensive abstract to be published in the workshop handout submitted to eratec [at] ira [dot] inaf [dot] it.

The abstracts will be made available as a workshop worksheet. Speakers will be asked to send a short abstract through the corresponding submission tool of the Workshop website by the abstract submission deadline and to provide an authorized copy of their presentation for publishing on the RadioNet3 Web pages soon after the presentation of their contributions.

The meeting will take place in Aula A of the Department of Physics and Astronomy "Garbasso building" in Largo Enrico Fermi, 2 - Florence. Please note that the Department is 300 m far from the headquarter of the Arcetri Astrophysical Observatory.
Information on how to get the Arcetri Astrophysical Observatory can be found in the webpage:
