IGS

The International GPS Service for Geodynamics is a service established by

the International Association of Geodesy (IAG).  IGS is based on about 50

globally distributed permanent GPS tracking sites and routinely provides high

quality orbits for all GPS satellites, Earth rotation parameters, contributions to

the determination of the tracking site coordinates in the International

Terrestrial Reference Frame (ITRF), and phase and pseudorange

observations in daily RINEX files for each IGS tracking site.
