VLBI Global Observing System (VGOS)
The International VLBI Service for Geodesy and Astrometry (IVS) has been developing the next generation of VLBI system – VLBI Global Observing System (VGOS). They have identified the need for modern, fast slewing, broadband radio telescopes to realise the goal of improving accuracy by a factor of 10 – from 1 cm down to 1 mm – across global baselines.
