The Vienna VLBI Software (VieVS) is a new state of the art VLBI analysis software written in MATLAB. It is developed at the Department of Geodesy and Geoinformation, Vienna University of Technology.
Registration: If you want to have access to VieVS, take a look at the
requirements for external users (terms.pdf) and send a letter to Johannes Böhm (signed
by the head of your institution) where you describe for which purposes you
would like to have access to VieVS. You can use the template.
Installation: Log in to vievs.hg.tuwien.ac.at using sftp (you will get the username and password once you are registred), and follow the instructions in the INSTALL.txt file. Or just download the whole
VieVS directory (or subdirectories when updating).
Starting VieVS: Start vievs.m in the WORK directory. Have fun!

The VieVS documentation (draft) can be found here. More information about special parts can be found in the documents in the DOC directory and in the presentations from the third VieVS user Workshop.
VieVS User Workshop:
The first VieVS user Workshop was held 7-9 September, 2010, at TU Vienna. The presentations from the Workshop can be downloaded from the Workshop homepage.
The second VieVS User Workshop was held on September 14-16, 2011.
The third VieVS User Workshop was held on September 11-13, 2012.
A Comparison Campaign was started with the goal to
compare different VLBI analysis software packages on the basis of the computed
delay and its partial derivatives. Find details at the the DeDeCC website.
VieTRF10a and VieCRF10a:
The Vienna Terrestrial Reference Frame (VieTRF10a) contains positions, and velocities assuming linear motion of stations and the Vienna Celestial Reference Frame (VieCRF10a) contains the positions of radio sources. They were estimated simultaneously in a common global adjustment by the software VieVS using VLBI observations since 1984. More details are provided in this document.
