VieVS days 2020 - webinar

:-D News entry at the Vienna Center for VLBI website including videos!

Monday, Sep 14

VieVS 3.2 including the data needed for the webinar can be downloaded as .zip from If you prefer to use your own running VieVS version just take the data from the single folders in and put them to the respective folders of your installation (Mind that VLBI_OPT has to be on the same level as the COMMON and VLBI directories, if you already started vievs once this folder already exists).

Tuesday, Sep 15 (Matthias Schartner)

  • 10:00-12:00: Scheduling and simulations with VieSched++ part I handout presentation
  • 13:00-15:00: Scheduling and simulations with VieSched++ part II

For an efficient participation you will need a PC or notebook with a recent Matlab installation (R2016b or later - mapping toolbox is mandatory, parallel processing toolboxes are highly recommended) and VieVS VLBI V3.2 as well as VieSched++ V1.1. We also strongly recommend to have a second screen (or second PC), because we will do exercises.

General information about VieVS can be found at, the software is available from (please refer to the respective to install the modules).
