The IGS collects, archives, and freely distributes Global Navigation Satellite System (GNSS) observation data sets from a cooperatively operated global network of IGS ground tracking stations.
IGS stations provide continuous tracking using high accuracy receivers and have data transmission facilities allowing for rapid (minimally: daily) data transmission to the data centers. The stations must meet physical and operational requirements as provided by the IGS Site Guidelines.
Station data is archived and distributed by the IGS Data Centers.
