Roll-out Status of the VGOS Network
Abstract
The member organizations of the International VLBI Service for Geodesy and Astrometry (IVS) operate an observational network of VLBI telescopes that currently consists of about 40 stations worldwide. This S/X VLBI network was developed mainly in the 1970s and 1980s. Due to the aging infrastructure but also because of demanding new scientific requirements, the larger IVS community planned and started to roll out a new VLBI system called VGOS (VLBI Global Observing System) at existing and new sites over the last few years. The roll-out effort is ongoing and it is anticipated that the VGOS network may become fully operational in the early 2020s. Once VLBI products can be derived from the new system in an operational manner, the VGOS network will replace the legacy S/X network as the production system of the IVS. In this presentation we describe the current status of the VGOS network and its anticipated evolution over the next several years.
