The main advantage of the VLBI technique over other space geodetic techniques is that our sources do not move. L05 Why do we do it? – A motivation for VLBI for Astrometry After this lecture you should be better informed about what is "out there" and what tools and mechanism may exist to help address the challenges in contemporary high-bandwidth VLBI. In order to make inter- and intracontinental VLBI work data from several stations needs to be combined, which introduces yet more possible dimensions of (in)compatibilities. The speed at which this data is generated and its sheer volume pose interesting problems for capturing and handling. In this lecture we'll focus on the signal processing steps and the handling of the digital data that is the result of that. L04: How do we store and transport the data? – Data acquisition and transport In this lecture we focus on the signal calibration used in VGOS. The signals suffer from system delays which are neither constant nor predictable. The signals pass through various components of the receiving system before they are digitized and time tagged. We go through the whole signal chain, starting from the radio telescope and receiver that collect radio signal and ending with the digital backend, where signal is sampled and digitized. This lecture will give overview on the VLBI equipment, specifically VGOS. L02 What do we use to observe? – VLBI stations, radio telescopes, receivers, backends The IVS activity and its components will be introduced. The introduction of the VGOS concept will be presented here. It explains what geophysical phenomena we can observe and study with this technique. This lecture gives a general overview of the role of Geodetic VLBI in Geodesy and Geoscience. L01 Why do we do it? – A motivation for VLBI for Geodesy and Geosciences The school program covers following topics The program consist of lectures and exercises developed with emphases on new VLBI Global Observing System (VGOS). The IVS Training School is organized by the IVS Committee on Education and Training (IVS CTE, more information at IVS CTE webpage )ĭue to the global pandemic the school will be organized in online format. This research school shall address these issues and provide the necessary training. At the same time, a new generation of VLBI researchers is emerging and efforts are necessary to convey research knowledge in VLBI to the new generation, both concerning the legacy system and the new system. Thus, VGOS will be of great importance for geosciences and global change research, e.g., the Global Geodetic Observing System (GGOS). VGOS promises to become a significant improvement in accuracy for the VLBI results. Currently, the VLBI technique is in a very exciting phase of renewal with equipment for the next generation VLBI technique, the VLBI Global Observing System (VGOS) being installed at several places world-wide. The aim of this training school is to prepare for the next generation VLBI, both in terms of the technical development, but also in terms of conveying knowledge between generations of researchers.
