# Welcome to the VieVS Wiki

The Vienna VLBI and Satellite Software (VieVS) is a state-of-the-art VLBI analysis software written in MATLAB. It is developed and maintained at the Department of Geodesy and Geoinformation, Vienna University of Technology.

This Wiki provides useful information on VieVS, e.g. a user manual, a user workshop page and current VieVS products. The VLBI fundamental Section gives an introduction to VLBI data analysis.

## 8th VieVS User Workshop 2017

The 8th VieVS users workshop was held from September 12 to 13, 2017 at the Technische Universität Wien. The focus was on practical exercises in terms of scheduling and analysing VLBI observations.Please find all the lecture material on the workshop page.

## New VieVS 3.0 Release

The new VieVS release (version 3.0) is available from now on (2017-06-12) ! VieVS 3.0 provides new analysis options and an improved usability. Please mind that VieVS now stands for Vienna VLBI and Satellite Software. This is due to the recent additions in terms of VLBI observations to satellites and upcoming activities in the field of Satellite Laser Ranging. Please find more information on our VieVS 3.0 release page.

We also have a new VieVS logo which is available in the Publications Section.

Please note: with the new software release we will change the way in which we provide the software to external users. VieVS is available via SFTP on a new server. SSH keys have to be used to log onto this machine in order to download the VieVS 3.0 program code and all the data required for analysis. A step-by-step description on how to access the server using SSH keys can be found here.
