Precise GPS Orbital Data from IGS: Current Status

The International GNSS Service (IGS) has further improved the quality of the products made available to the GNSS community. The accuracy of the Final gps kids watch Orbits (available weekly with a delay of about two weeks) from IGS is now about 2 centimeters, based on an analysis of discontinuties between separate daily products and independent laser-tracking data. Errors in the along- and cross-track orbital directions are about 75% larger than radially, but correlations between components are significant.
