IGS Stations

The IGS collects, archives, and freely distributes Global Navigation Satellite System (GNSS) observation data sets from a cooperatively operated global network of 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.

IGS Guidelines

The IGS network is a collection of heterogeneous stations operated by many different organizations pooling their resources under the IGS umbrella for the common good. Stringent rules are inconsistent with the voluntary nature of the IGS. However, participating stations must agree to adhere to the standards and conventions contained herein, which ensure the consistent high quality of the IGS network and products. Of particular importance to the IGS is the stable, long-term operation of the network.

The latest version of such standards are fully described here: IGS Site Guidelines July 2015
