NIST International GNSS Service Tracking Site

IGS Network

The NIST Time and Frequency Division has had two stations in the IGS Tracking Network: NIST and NISU.

The International GNSS Service (IGS) compiles satellite data from over 200 sites worldwide for multiple research and educational applications.

The station NISU was operational in the IGS from 2004 to 2009. The station NIST has been our IGS station since 2008.
For more information on station NISU in the IGS, see the IGS NISU page.
