The IGS Workshop, scheduled for September 2021 by the International GNSS Service (IGS), has been postponed to 2022. The IGS Central Bureau voted for the postponement in December during its governing board meeting. The IGS Workshop, originally intended to take place 2020, was postponed to 2021 because of travel restrictions associated with COVID-19. The dates of the workshop will be determined later. The IGS is a service of the International Association of Geodesy (IAG), its Global Geodetic Observing System (GGOS), The International Union of Geodesy and Geophysics (IUGG), and a network member of the International Science Council (ISC) World Data System (WDS).
